[PATCH] ARM: dts: am57xx-beagle-x15: fix HDMI LS_OE GPIO

LS_OE GPIO was changed from gpio6_28 to gpio2_30 for the Rev B1 board,
and the current .dts file has the old GPIO.

Rev B1 is the earliest board supported, so we can just change the .dts.

This fixes "omapdss error: HDMI I2C Master Error" which causes failure
to read EDID from the monitor.
