arm64: dts: ti: k3-am62a7-sk: Enable Main UART wakeup
The Main UART can resume from suspend to RAM states when PIN_WKUP_EN
is enabled. Add the necessary pins needed to wakeup the system. Add the
system idle states that the Main UART can wakeup the system from.
The UART driver uses the "default" pinctrl state when the system is
active. In the suspend hook, if the UART is wakeup enabled, the "wakeup"
pinctrl state is selected by the UART driver in order to allow wakeup.
Upon resume, the default pinctrl state is selected again.
