The RPC and RPCD2 core clocks were added to the sections for internal
core clocks, while they are core clock outputs, visible from DT.
Move them to the correct sections.
Rename the ".rpc" clock on R-Car S4 to "rpc".
Fixup nearby whitespace to increase uniformity.

The clock sources of the AXI-bus clock (266.66 MHz) used for Audio-DMAC
DMA transfers are:
Channel R-Car H3 R-Car M3-W R-Car M3-N R-Car E3
---------------------------------------------------------------
Audio-DMAC0 S1D2 S1D2 S1D2 S1D2
Audio-DMAC1 S1D2 S1D2 S1D2 -
As a result, change the parent clocks of the Audio-DMAC{0,1} module
clocks on R-Car H3, R-Car M3-W, and R-Car M3-N to S1D2, and change the
parent clock of the Audio-DMAC0 module on R-Car E3 to S1D2.

After recent reworking of Z and Z2 clk handling
CLK_TYPE_GEN3_Z and CLK_TYPE_GEN3_Z2 have come to have precisely
the same meaning. Remove this redundancy by eliminating the latter.
This is not expected to have any run-time effect.

Parameterise the offset of control bits within the FRQCRC register
for Z and Z2 clocks.
This is in preparation for supporting the Z2 clock on the R-Car E3

other, already, supported SoCs.
