The clock sources of the AXI BUS clock (266.66 MHz) used for SYS-DMAC
DMA transfers are:
Channel R-Car H3 R-Car M3-W R-Car M3-N
-------------------------------------------------
SYS-DMAC0 S0D3 S0D3 S0D3
SYS-DMAC1 S3D1 S3D1 S3D1
SYS-DMAC2 S3D1 S3D1 S3D1
As a result, change the parent clocks of the SYS-DMAC{1,2} module clocks
on R-Car H3, R-Car M3-W, and R-Car M3-N to S3D1.
NOTE: This information will be reflected in a future revision of the
R-Car Gen3 Hardware Manual.

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.

R-Car Gen3 Hardware Manual Rev.0.52 documents the relation between the
MD13 and MD14 mode pins, and the OSC EXTAL predivider, as used by the
OSC and RINT RCLK clocks. Hence augment the configuration structure
with all documented predivider values.
According to R-Car Gen3 Hardware Manual Rev.1.00, R-Car M3-N does not
have the CPG_RCKCR register. Change the OSC and RINT clock definitions
to use the OSC EXTAL predivider instead, which is supported on all R-Car
M3-N SoC revisions.
Inspired by a patch in the BSP by Takeshi Kihara
<takeshi.kihara.df@renesas.com>.

All other internal clock names have a period prepended.
Hence rename the internal RCLK from "rint" to ".r", and move it to the
section where all other internal clocks are defined.

R-Car M3-N does not have the DU2 unit but it has DU3 instead.
Fix the module clock definition to reflect that.
