arm64: dts: ti: k3-am62p5-sk: Fix pinmux for McASP1 TX

commit 327467d2c3873fbb91487e61d3a6957e4e607e74 from
git://git.ti.com/ti-linux-kernel/ti-linux-kernel.git



On SK-AM62P, McASP1 uses two pins for communicating with the codec over
I2S protocol. One of these pins (AXR0) is used for audio playback (TX)
so the direction of the pin should be OUTPUT.
