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.

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.

When trying to use I2C7 on R-Car E3:
renesas-cpg-mssr e6150000.clock-controller: Cannot get module clock 1003: -2
i2c-rcar e6690000.i2c: failed to add to PM domain always-on: -2
i2c-rcar: probe of e6690000.i2c failed with error -2
Unlike other R-Car Gen3 SoCs, R-Car E3 has more than 7 I2C bus
interfaces. Add the forgotten module clock for the 8th instance to fix
this.

According to R-Car Gen3 Hardware Manual Rev.1.00, R-Car E3 has the
RCLK Frequency Control Register (RCKCR), which determines the OSC and
RINT predivider values, and selection of the RCLK clock source between
RINT and the On-Chip Oscillator.
Hence change the OSC and RINT clock definitions to use the RCKCR
divider, and add the missing On-Chip Oscillator and RCLK clock source
switching logic.
