ARM: dts: Fix igepv5 audiopwon-gpio
Playing audio works on omap5-uevm, but produces an "Unhandled fault: imprecise external abort (0x1406) at 0x00000000" error on igepv5. Looks like the twl6040 audpwron GPIO pin is different for these boards. Let's fix the issue by configuring the audpwron in the board specific dts file.
