[PATCH v1] mach-k3: add eMMC FS boot support for am62[ap]

[Anshul Dalal]

This makes spl_mmc_boot_mode consistent across am62x, 62a and 62p.

If MMCSD_MODE_EMMCBOOT is returned, FS boot fails since it checks for FS
on the hardware partitions, not the UDA. So to allow FS boot from EMMC,
the function should return MMCSD_MODE_FS instead which allows us to read
from FS on the UDA.
