arm64: renesas: Enable CR52 remoteproc on R-Car R8A779G0 V4H

Enable remoteproc command and APMU remoteproc driver to start Cortex-R52
cores from U-Boot command line. Code on the Cortex-R52 #0 can be started
as follows, code on other cores can be started by passing the correct ID
to 'rproc load' and 'rproc start' to select the core:

"
=> rproc init
=> rproc list
0 - Name:'rcar-apmu-cr52.0-apmu@e6170000' type:'internal memory mapped' supports: load start stop reset is_running
1 - Name:'rcar-apmu-cr52.1-apmu@e6170000' type:'internal memory mapped' supports: load start stop reset is_running
2 - Name:'rcar-apmu-cr52.2-apmu@e6170000' type:'internal memory mapped' supports: load start stop reset is_running
=> rproc load 0 0xeb200000 0x10000
Load Remote Processor 0 with data@addr=0xeb200000 65536 bytes: Success!
=> rproc start 0
