880c3fa319 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.

Describe the various clocks used by the SPI Multi I/O Bus Controller
(RPC-IF) on the R-Car E3 SoC: RPCSRC internal clock, RPC{,D2} clocks
derived from it, and RPC-IF module clock.

d843e61e0e clk: renesas: r8a7799[05]: Add MLP clocks
Add clocks for MLP modules on Renesas R-Car E3 and D3 SoCs.

Similar to other R-Car Gen3 SoC, exact information on the parents of MLP
clocks on E3 and D3 is not available.  However, since the parents of
these clocks are not anyhow software-controllable, the only harm from
this is inexact information exported via debugfs.  So just keep the
parent set in the same way as with other Gen3 SoCs.

According to the R-Car Gen3 Hardware Manual Errata for Rev. 1.50 of Feb
12, 2019, the DRIF clocks have been renamed as follows:

    DRIF0 to DRIF00
    DRIF1 to DRIF01
    DRIF2 to DRIF10
    DRIF3 to DRIF11
    DRIF4 to DRIF20
    DRIF5 to DRIF21
    DRIF6 to DRIF30
    DRIF7 to DRIF31

Therefore, this patch renames the DRIF clocks from DRIFn to DRIFmm.

b9df2ea2b8 clk: renesas: rcar-gen3: Correct parent clock of Audio-DMAC
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.

NOTE: This information will be reflected in a future revision of the
      R-Car Gen3 Hardware Manual.

RCLK Frequency Control Register (RCKCR), which determines the OSC and

divider, and add the missing On-Chip Oscillator and RCLK clock source
