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.

According to the R-Car Gen3 Hardware Manual Rev. 1.00, and the RZ/G2
Hardware Manual Rev. 0.61, the parent clock of the HS-USB module
clocks on R-Car Gen3 and RZ/G2 SoCs is S3D2.

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.
As suggested by Geert Uytterhoeven.

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
(r8a77990) SoC which uses a different offset for control bits to
other, already, supported SoCs.
As suggested by Geert Uytterhoeven.

Parameterise Z and Z2 clock fixed divisor to allow clocks with a fixed
divisor other than 2, the value used by all such clocks supported to date.
This is in preparation for supporting the Z2 clock on the R-Car E3
(r8a77990) SoC which has a fixed divisor of 4.
