Subject: [PATCH 3/5] arm64: dts: ti: k3-am62: add dedicated wakeup
 controller compatible

Each syscon node must come with a dedicated/specific compatible, which
is also reported by dtbs_check:

  k3-am62-lp-sk.dtb: syscon@...00000: compatible: ['syscon', 'simple-mfd'] is too short

Add one for the TI K3 AM62 wakeup system controller.
