[PATCH 37/41] ARM: dts: am57xx-beagle-x15-common: Set MMC2 IO voltage to 3.3V

MMC2 interface on AM57xx Beagle-x15, connected to
onboard eMMC, has IO voltage fixed to 3.3V.

Add no-1-8-v device-tree property to mmc2 node
in the board's device-tree file to reflect
this.

Note that the AM57xx SoC itself supports dual-voltage
on MMC2. The limitation above is due to the board.
