[U-Boot] [PATCH] rockchip: Disable SPL_MMC_SUPPORT if ROCKCHIP_SPL_BACK_TO_BROM is enabled.

[Sandy Patterson]

CONFIG_SPL_MMC_SUPPORT is used pretty much for every board except jerry,
so we can refactor the define into rk3288_common.h. Then only define it if
we are using using the Bootrom to load the non SPL U-Boot.

With this change the SPL binary shrinks from 32k to 23k when
ROCKCHIP_SPL_BACK_TO_BROM is enabled. This has been tested on the rock2
board. It should work with any rk3288 though since the bootrom is
loading the SPL already it should load the main U-Boot as well.

Rock2 has been tested with ROCKCHIP_SPL_BACK_TO_BROM So enabled for
rock2.
