Merge patch series "Enable MMC UHS modes"

Browse Source 
Judith Mendez <jm@ti.com> says:

This patch series adds config options for Sitara K3 boards
to support MMC UHS modes.

While testing with SD card boot and eMMC boot,
found missing eMMC boot support for am62ax in am62a7_init,
patch 1/7, and missing config option to support eMMC boot.

While we are here, for am62ax, enable config option to
change MMC bus modes and enable r5 SDHCI ADMA for faster boot
time.

Also for all k3 Sitara boards, cleanup MMC ENV configs that
are no longer needed since we no longer load env from MMC
device.
