For most devices the boot mode maps directly to the boot
device. For MMC this is not the case as we have two MMC
boot modes and two MMC boot devices (ports). Check the
boot port to determine which MMC device was our boot
device. Make this change for both primary and secondary
boot modes.

Read the boot mode register to find the boot mode. Only use eMMC boot0
mode when the mode is eMMC boot (called BOOT_DEVICE_MMC1 currently due
to current conflating of boot mode and boot device), and not iff the
boot device is MMC port 0.
