This moves the sniper board from the lge to lg, in order to match the devicetree

With the previous implementation, rebooting without registering a recognized
reboot mode would end up with U-Boot checking for a valid power-on reason, which
might result in the device turning off (e.g. with no USB cable attached and no
buttons pressed).
Since this approach is not viable (breaks reboot in most cases), the validity of
the reboot reason is checked (in turn, by checking that a warm reset happened,
as there is no magic) to detect a reboot and the 'o' char is recognized to
indicate that power-off is required. Still, that might be overridden by the
detection of usual power-on reasons, on purpose.

reboot mode (despite registering the magic) would end up with U-Boot checking
for a valid power-on reason, which might result in the device turning off (e.g.
with no USB cable attached and no buttons pressed).
This was designed to catch reboots that are actually intended to be power-off,
something that old Android kernels do, instead of properly turning the device
off using the TWL4030.
However, since this approach is not viable (breaks reboot in most cases), the
validity of the reboot mode magic is checked to detect a reboot and the 'o' char
is recognized to indicate that power-off is required. Still, that might be
overridden by the detection of usual power-on reasons, on purpose.

Now everything is done to load a raw U-Boot proper image instead of
an mkimage-processed one (as far as I tested on NAND, eMMC, NOR).
The SPL already knows the load address of the U-Boot proper without
parsing its uImage header because the load address is defined by
CONFIG_SYS_TEXT_BASE, assuming that the two images are generated from
the same build.
My main motivation of this switch is to use u-boot-with-spl.bin, a
concatenation of u-boot-spl.bin and u-boot.bin. (I wish there were
a concatenation of u-boot-spl.bin and u-boot.img...) Anyway, this
commit would be useful for one-shot image burn.

For ARM32 architecture, CONFIG_DEBUG_LL is available for early
low-level debugging (and actually UniPhier 32bit SoCs use it), but
ARM64 architecture does not support it. Instead, CONFIG_DEBUG_UART
is available as an architecture-independent debug facility.
This commit supports it on all the UniPhier SoCs (including the new
ARMv8 SoCs), which is very useful for new SoC bringups.

The System Control block moved to a completely different register

These commands are not necessarily needed for usual operations
(they are useful in case of DDR memory trouble), but enabling them
by default would be nice in terms of the compilation test coverage.
They are small enough, so limited impact on the memory footprint.

Due to some hardware guy's awful work, this version is not compatible
with v3.6: the logic of BIT(0) of the reset logic is inverted! (and
v3.6.10 is horribly wrong in multiple ways), but this is what we have
to solve now.
The v3.6 expects 0x0000 set to the register for reset de-assertion,
while v3.6 does 0x0001.
This commit (ab)uses another bug of v3.6.10 to work around the issue.
The UniPhier System Bus is a 16-bit bus, which this support card is
connected to. A 32-bit write to the bus (writel() function call) is
divided into two 16-bit write transactions, with LSB the first. What
is amazing for v3.6.10 is that access to address 4N + 2 goes to 4N
(Jesus Christ!).
For clarification, things are like this:
writel(0x00010000, MICRO_SUPPORT_CARD_RESET);
is done with two bus transactions as follows
[1] write 0x0000 to address MICRO_SUPPORT_CARD
[2] write 0x0001 to address MICRO_SUPPORT_CARD + 2
For v3.6, [1] is written to the register and [2] is correctly ignored
because there is nothing at the address MICRO_SUPPORT_CARD + 2. This
is what we expect.
For v3.6.10, [1] is written to the reset register and then [2] is
over-written to the same register due to the bus access bug.
For the latter, it produces a glitch signal to the BIT[0], so the
device state is lost due to the reset pulse. This solution only
works for the start-up code.

There is a bunch of duplication in the System Bus Controller init
code. Roughly, there are two types in the SBC mode: Adress/Data
Multiplex Mode and Save Pins Mode. Consolidate per-SoC functions
into the two, plus per-SoC optional init code.

The current CONFIG names like "CONFIG_ARCH_UNIPHIER_PH1_PRO4" is too

This TODO is no longer useful. CONFIG_SYS_NS16550_SERIAL is just
ignored on DM serial.
If one wants to use the 16550A UART device on the UniPhier Micro
Support Card, it can be enabled by CONFIG_SYS_NS16550 via Kconfig.
Please notice CONFIG_SPL_OF_TRANSLATE must be enabled as well and
the device tree must be treaked in order to use the NS16550 serial
on SPL.

The function spl_parse_image_header() falls back to a raw image
if the U-Boot header is missing and CONFIG_SPL_PANIC_ON_RAW_IMAGE
is undefined. While, mmc_load_image_raw_sector() only accepts a
U-Boot legacy image or an FIT image, preventing us from loading a
raw image.

The license command isn't usually built and has a few problems:
- The rules to generate license.h haven't worked in a long time,
re-write these based on the bmp_logo.h rules.
- 'tok' is unused and the license text size has increased
- bin2header.c wasn't grabbing unistd.h to know the prototype for
read().
