arm64: dts: ti: k3-am69-sk: Fix UART pin type and macro type

Along fixing wkup UART RTS and TX pins as OUTPUT instead of INPUT
updating J784S4 macro for pin mux instead of J721S2.

Fixes: 45299dd1 ("arm64: dts: ti: k3-am69-sk: Add mcu and wakeup uarts")
Fixes: 08ae12b6 ("arm64: dts: ti: k3-am69-sk: Enable wakeup_i2c0 and eeprom")
