board/ti/am6{2, 4}x: add missing uboot.hash file
Arnout noticed during the review that uboot.hash was missing from
BR2_GLOBAL_PATCH_DIR.
"The hash for 2024.01 is currently in boot/uboot/uboot.hash, but as soon as we
update the U-Boot version, it will no longer be. So to be future safe, we should
add a local override of the uboot hash file as well (which is simply identical
to uboot.hash)."
This is required since BR2_DOWNLOAD_FORCE_CHECK_HASHES is now enabled.
