Add a command (for the app and payload) to display the tables provided
by EFI. Note that for the payload the tables should always be present, so
an error message is unnecessary and would bloat the code.

At present the 'efi' command only works in the EFI payload. Update it to
work in the app too, so the memory map can be examined.

At present this function requires a pointer to struct efi_entry_memmap
but the only field used in there is the desc_size. We want to be able
to use it from the app, so update it to use desc_size directly.

Move this out of the common header and include it only where needed. In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly. Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

* Eliminate superfluous enum value EFI_TABLE_END.
* Use correct variable type for the memory type.
* Check validity of memory type.
* Make efi_build_mem_table static.

The UEFI 2.8 specification has introduced the EFI_MEMORY_SP memory
attribute. Add it to the 'efidebug memmap' and 'efi mem' commands.

Move this header out of the common header.

We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.
Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.
This requires quite a few header-file additions.

These don't need to be in common.h so move them out into a new header.
Also add some missing comments.

With this update, the memory attributes are in sync with Linux
kernel v4.18-rc4. They also match page 190 of UEFI 2.7 spec [1].

Starting with commit 867a6ac86dd8 ("efi: Add start-up library code"),
sparse constantly complains about truncated constant value in efi.h:
include/efi.h:176:35: warning: cast truncates bits from constant value (8000000000000000 becomes 0)
This can get quite noisy, preventing real issues to be noticed:
$ make defconfig
*** Default configuration is based on 'sandbox_defconfig'
$ make C=2 -j12 2>&1 | grep truncates | wc -l
441
After the patch is applied:
$ make C=2 -j12 2>&1 | grep truncates | wc -l
0
$ sparse --version
v0.5.2
Following the suggestion of Heinrich Schuchardt, instead of only
fixing the root-cause, I replaced the whole enum of _SHIFT values
by ULL defines. This matches both the UEFI 2.7 spec and the Linux
kernel implementation.
Some ELF size comparison before and after the patch (gcc 7.3.0):

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.

Now that they are in their own directory, we can remove this prefix.
This makes it easier to find a file since the prefix does not get in the
way.
