At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.
Move the compatibility features into a separate header file.

The GXBB pinctrl is missing pins related to HDMI, namely hot plug
detection (hpd) and I2C (sda + scl).
This fixes HDMI support for GXBB in u-boot.

drive-strength-microamp is a new feature needed for G12A SoC.
the default DS setting after boot is usually 500uA and it is not enough for
many functions. We need to be able to set the drive strength to reliably
enable things like MMC, I2C, etc ...

In order to support the "pinmux status" command, use the common functions
to get the pins count and names, and add the AXG specific function to get
the current function from registers.

The GPIO_TEST_N was in the wrong pmx group table, move it back with the AO
groups, GPIODV_18 was missing, add it back, and finally the GPIOCLK_*
group names were missing.

Periphs bank offset must be applied on all pins and
PMX bank to prevent issue in meson_pinconf_set call.
Without offset on pins when a call to pinconf is done
meson_gpio_calc_reg_and_bit return wrong offset.
To avoid breaking pmx function offset is needed in pmx bank structure too.

Adding pinconf support is necessary to enable boot from SPI
without breaking the eMMC. When booting from SPI, the ROM code
leave pull downs on the eMMC pad.
We need to set pinconf provided in DT to solve this

The pin number (first and last) in the bank definition is missing the
pin base offset shifting. This is causing a miscalculation when
retrieving the register and pin offsets in the GPIO driver causing the
'gpio' command to drive the wrong pins / GPIOs in the second GPIO chip
(the AO bank is driven correctly because the shifting is already 0).

The macros used to set the direction of the GPIO pins are misused,
resulting in a wrong behavior when trying to read the GPIO input level
from U-Boot.
A better macro is also used when setting the output direction.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

It is good practice to include common.h as the first header. This ensures
that required features like the DECLARE_GLOBAL_DATA_PTR macro,
configuration options and common types are available.
Fix up some files which currently don't do this. This is necessary because
driver model will soon start using global data and configuration in the
dm/read.h header file, included via dm.h. The gd->fdt_blob value will be
used to access the device tree and CONFIG options will be used to
determine whether to support inline functions in the header file.

At present devices use a simple integer offset to record the device tree
node associated with the device. In preparation for supporting a live
device tree, which uses a node pointer instead, refactor existing code to
access this field through an inline function.
