arm64: dts: renesas: Switch to remap drivers on R-Car Gen5 R8A78000 X5H

Point every direct user of SCMI clock protocol at CPG node instead
of SCMI clock protocol node. Point every direct user of SCMI reset
and power domain protocol at a matching newly introduced MDLC node
instead of the SCMI reset and power domain protocol nodes.

This allows the CPG and MDLC remap drivers bound to CPG node and MDLC
nodes to remap between DT clock, reset and power domain IDs and SCMI
clock, reset and power domain IDs. This makes U-Boot on R-Car X5H
compatible with multiple SCP firmware versions. Currently supported
versions of SCP firmware are 4.28, 4.31 and 4.32.
