clk: renesas: rcar-gen3: Add ADG clocks

R-Car Sound needs to enable "ADG" on RMSTPCR9/SMSTPCR9 bit 22 to use
clk_i which came from the internal S0D4 or ZA2 clock.

clk: renesas: Move RPC core clocks

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.
