commonlib/storage: Add common eMMC functions
Now that multiple platforms are trying to initialize eMMC in coreboot
instead of depthcharge, lets move common functionality into commonlib
instead of copying the same functionality between multiple platforms.
Note for consistency, changed name of set_early_mmc_wake_status() to
mmc_set_early_wake_status(). Also adding an mmc_send_cmd1() function
for retrieving the Operating Conditions Register (OCR) contents.
BUG=b:218406702
BRANCH=None
TEST=emerge-herobrine coreboot chromeos-bootimage
flash onto villager device and make sure still boots ChromeOS
