ARM: dts: AM33XX: Set pinmux for clkout2 pad used for clock output

xdma_event_intr1.clkout2 pad can be used to source clock from either 32K OSC or any of the PLL (except MPU) outputs. On the existing AM335x based boards (EVM, EVM-SK and Bone), this pad is used to feed the clock to audio codes. So, this patch configures the pinmux to get clkout2 on the pad.
