arm64: dts: ti: k3-am62a7-sk: Set wakeup-source system-states
The CANUART pins of mcu_mcan0, mcu_mcan1, mcu_uart0 and wkup_uart0 are
powered during Partial-IO and I/O Only + DDR and are capable of waking
up the system in these states. Specify the states in which these units
can do a wakeup on this board.
Note that the UARTs are not capable of wakeup in Partial-IO because of
of a UART mux on the board not being powered during Partial-IO.
Add pincontrol definitions for mcu_mcan0 and mcu_mcan1 for wakeup from
Partial-IO. Add these as wakeup pinctrl entries for both devices.
