[PATCH v2 5/5] arm64: dts: ti: k3-am62a: use a specific MCU controller compatible

SoCs (and associated MCUs) should use dedicated compatibles for their
nodes, not re-use one coming from an another SoC.  Using an incorrect
compatible does not allow to properly match/validate children of the
MCU device and causes dtbs_check warnings:

  k3-am62a7-sk.dtb: syscon at 43000000: 'syscon at 4008', 'syscon at 4018' do not match any of the regexes:
    '^chipid@[0-9a-f]+$', '^clock-controller@[0-9a-f]+$', '^mux-controller@[0-9a-f]+$', 'phy@[0-9a-f]+$', 'pinctrl-[0-9]+'
