arm64: dts: ti: k3-am62p5-sk: Remove CTS/RTS from wkup_uart0 pinctrl

Browse Source 
wkup_uart0 is a reserved node that is used by Device Manager firmware.
Only TX and RX pins are required for the firmware and enabling pinctrl
for CTS and RTS breaks the wakeup functionality of wkup_uart0. Drop the
conflicting muxes.
