Add a series posted to upstream mailing lists that makes the GRUB
text-mode console faster by implementing video damage tracking [1].
Refresh the config files to include its new VIDEO_DAMAGE Kconfig.
Patch 7/7 upstream has a tiny conflict with "Improve UEFI experience"
series we already have, but it's only in the diff context. No changes
other than fixing that.

Set revision to the commit hash of the v2022.10 release, and run "make
olddefconfig" for all boards to refresh the configs.

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 Samsung Chromebook Plus (v1),
also known as "chromebook_kevin" in the U-Boot upstream defconfigs. Also
adds a shared "gru" board directory to share with others having the same
baseboard.
It uses v2022.07 with some quality-of-life patches. The first one is a
clock adjustment to match coreboot clocks for the video output, the
second one is a series about text cursor support and larger fonts. These
are because the display has a high resolution of 2400x1600 at 12.3".
The config has the following diffconfig from the upstream defconfig for
this board:
# For chainloading from depthcharge like a payload (RW_LEGACY).
# Not everything might be necessary, but didn't test without these.
