On DRA7 family SoCs, MMC1 controller supports SDR104,
SDR50, DDR50, SDR25 and SDR12 UHS modes (These UHS modes
are not supported in beagle-x15 because it's not possible
to switch IO lines supply voltage to 1.8v).

MMC2 controller supports HS200 and DDR modes. (Since some of the
boards like am57xx-evm reva3, beagle-x15 and am57xx idk has
3.3v line connected to IO lines, HS200 cannot be supported
in these boards).

MMC3 controller supports SDR12, SDR25 and SDR50 modes.

MMC4 controller supports SDR12 and SDR25 modes.

Add these supported modes in device-tree file.
