Subject: [PATCH v2 1/4] arm64: dts: ti: k3-j72xx-mcu-wakeup: add dedicated wakeup controller compatible

From: Jan Kiszka <jan.kiszka@...mens.com>

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

  k3-j7200-common-proc-board.dtb: scm-conf@...00000: compatible: ['syscon', 'simple-mfd'] is too short

Add one for the TI K3 AM654 MCU wakeup system controller used in J72xx
SoCs.
