GPT partition tables include two bytes worth of vendor defined
attributes, per partition. ChromeOS and Qualcomm both use these (with
different encoding!) to handle A/B slot switching with a retry counter.
Expose these via the disk_partition struct so that they can be parsed by
the relevant board code.
This will be used on Qualcomm boards to determine which slot we're
booting on so that we can flash capsule updates to the correct one.

Since commit 56670d6fb8 ("disk: part: use common api to lookup part
driver") part_get_info_by_name_type() ignores the part_type parameter
used to restrict the partition table type.
omap_mmc_get_part_size() and part_get_info_by_name() are the only
consumers.
omap_mmc_get_part_size() calls with part_type = PART_TYPE_EFI because at
the time of implementation a speed up could be gained by passing the
partition table type. After 5 years experience without this restriction
it looks safe to keep it that way.
part_get_info_by_name() uses PART_TYPE_ALL.
Move the logic of part_get_info_by_name_type() to part_get_info_by_name()
and replace the function in omap_mmc_get_part_size().

Some defconfig enables CMD_PART even if none of any partition table
types (CONFIG_*_PARTITION) are enabled.
This will lead to the size growth in SPL/TPL code since disk/part.c

We will change disk/Kconfig later so that CONFIG_PARTITIONS is only
enabled when, at least, one of CONFIG_*_PARTITION is enabled.

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.
