Hi All,

This patch series aims to add the CPG support for the Renesas
RZ/V2H(P) SoC.

Im sending this as an RFC as I have dropped the module clk macros to
avoid adding reserved macros and instead now using the combination of
register index and bits as unique number for clks and resets.

v1->RFC v2
- Updated commit message
- Updated description for binding as suggested by Geert
- Updated descriptions for clocks and resets property
- Renamed extal->qextal
- Updated '#power-domain-cells' value
- Dropped the module clocks and just added the core clocks
- Introduced family specific config option
- Now using register indexes for CLKON/CLKMON/RST/RSTMON
- Introduced PLL_CONF macro
- Dropped function pointer to get PLL_CLK1/2 offsets
- Added range check for core clks
- Dropped NULLified clocks check
- Dropped pll_clk1/clk2_offset
- Made r9a09g057_mod_clks/r9a09g057_resets as static const
