u-boot: Add kevin chromebook configs 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.
