[PATCH 2/3] rockchip: add support for veyron-speedy (ASUS Chromebook C201)

["Marty E. Plummer" <hanetzer-zVALfsKDk1AS+FvcfC7Uqw@public.gmane.org>]

This adds support for the ASUS C201, a RK3288-based clamshell
device. The device tree comes from linus's linux tree at
87ef12027b9b1dd0e0b12cf311fbcb19f9d92539. The SDRAM parameters
are for 4GB Samsung LPDDR3, decoded from coreboot's
src/mainboard/google/veyron/sdram_inf/sdram-lpddr3-samsung-4GB.inc

Signed-off-by: Marty E. Plummer <hanetzer-zVALfsKDk1AS+FvcfC7Uqw@public.gmane.org>
