Merge all boards into a common "default" tree, currently for v2022.07.
This ends up applying the "Improve UEFI experience on DM_VIDEO" series
to everything, so refresh the configs for the new options.

This adds U-Boot configuration for the Acer Chromebook 13 (CB5-311,
C810), also known as "nyan_big" in the U-Boot upstream defconfigs. Also
adds a shared "nyan" board directory to share with others having the
same baseboard. The config is almost the same as upstream defconfig, but
with REMAKE_ELF and POSITION_INDEPENDENT enabled.
Untested since I don't have the nyan big chromebook.
