include: android_bootloader_message.h: Minimize the diff to AOSP
Perform the following updates: - Relocate the commit id from the file to the description of U-Boot commit. The AOSP commit is c784ce50e8c10eaf70e1f97e24e8324aef45faf5. This is done to avoid stale references in the file itself. The reasoning is in https://patchwork.ozlabs.org/patch/1098056/#2170209. - Minimize the diff to AOSP, to decrease the effort of the next AOSP backports. The background can be found in: https://patchwork.ozlabs.org/patch/1080394/#2168454. - Guard the static_assert() calls by #ifndef __UBOOT__ ... #endif, to avoid compilation failures of files including the header.
