Subject: [PATCH 4/5] arm64: dts: ti: k3-am65-mcu: add dedicated wakeup
 controller compatible

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

  k3-am654-base-board.dtb: scm-conf@...00000: compatible: ['syscon', 'simple-mfd'] is too short

Add one for the TI K3 AM654 MCU wakeup system controller.

Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>
