This adds U-Boot configuration for the Samsung Chromebook - XE303, also
known as "snow" in the U-Boot upstream defconfigs. Also adds a shared
"daisy" 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 snow chromebook.
