ARM: dts: omap3-igep00x0: Fix UART2 pins that aren't common.
UART2 is used to connect the processor with the bluetooth chip, these pins
are not common between IGEPv2 boards and IGEP COM MODULE boards. This patch
muxes the correct pins for every board and removes UART2 configuration from
common omap3-igep.dtsi file.
