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.

We have a large number of places where while we historically referenced
gd in the code we no longer do, as well as cases where the code added
that line "just in case" during development and never dropped it.

The goal of this patch is to clean up the code related to choosing SPL
MMC boot mode.
The spl_boot_mode() now is called only in spl_mmc_load_image() function,
which is only compiled in if CONFIG_SPL_MMC_SUPPORT is enabled.
To achieve the goal, all per mach/arch implementations eligible for
unification has been replaced with one __weak implementation.

Right now the SPL is trying to load u-boot based on defines, i.e. one
has to define CONFIG_SPL_NAND_SIMPLE to boot from NAND,
or CONFIG_SPL_SPI_LOAD to boot from SPI FLASH, etc...
This prevent us from having a single SPL image that is able to boot from
all media, and one need to build an image for each medium. This
commit is replacing the #ifdef that select the boot medium by reading
the value of the boot pins (via the BOOTCFG register).
Now a single SPL image will be able to read from the boot pin to know
which device should be used to load u-boot.

The SPL code already knows which boot device it calls the spl_boot_mode()
on, so pass that information into the function. This allows the code of
spl_boot_mode() avoid invoking spl_boot_device() again, but it also lets
board_boot_order() correctly alter the behavior of the boot process.
The later one is important, since in certain cases, it is desired that
spl_boot_device() return value be overriden using board_boot_order().
