[ 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
