arm64: dts: ti: k3-am62a-wakeup: Configure ti-sysc for wkup_uart0
Similar to am62-wakeup, am62a-wakeup is capable of wakeup from
wkup_uart0. ti-sysc manages the sysconfig registers while
wkup_uart0 is only a portion of the register space.
See the link below for the upstream version of this patch for am62.
