arm64: dts: ti: k3-j784s4-evm: Fix UART pin type and macro type

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

Fixes: 5dfbd1d ("arm64: dts: ti: k3-j784s4-evm: Enable wakeup_i2c0 and eeprom")
Fixes: 6fa5d37 ("arm64: dts: ti: k3-j784s4-evm: Add mcu and wakeup uarts")
