arm64: dts: ti: k3-am62p-mcu/wakeup: Disable MCU and wakeup R5FSS nodes
[ Upstream commit dfc90e5f1a0fe0f8124521bc1911e38aa6cd9118 ]
K3 Remoteproc R5 driver requires reserved memory carveouts and
mailbox configuration to instantiate the cores successfully.
Since this is a board level dependency, keep the R5 subsytem
disabled at SoC dtsi, otherwise it results in probe errors like
below during AM62P SK boot:
r5fss@79000000: reserved memory init failed, ret = -22
r5fss@79000000: k3_r5_cluster_rproc_init failed, ret = -22
r5fss@78000000: reserved memory init failed, ret = -22
r5fss@78000000: k3_r5_cluster_rproc_init failed, ret = -22
