G clock is sourced from PLL3 and PLL6. The output of the mux is
connected to divider.
This patch adds a mux and divider for getting different rates from
this clock sources.

Core clock "I" is sourced from CPG_PL1_DDIV divider as per HW manual
Rev.1.00.
This patch adds clock divider table "dtable_1_8" and switches to
DEF_DIV for "I" clock.

Ethernet reference clock can be sourced from PLL5_FOUT3 or PLL6. Add
support for ethernet source clock selection using SEL_PLL_6_2 mux.
This patch also renames the PLL5_DIV2 core clock to PLL5_250 to match
with the register description as mentioned in RZ/G2L HW manual (Rev.1.00).

Add IA55_CLK and DMAC_ACLK as critical clocks.
Previously it worked ok, because of a bug in clock status function
and the following patch in this series fixes the original bug.
Fixes: c3e67ad6f5 ("dt-bindings: clock: r9a07g044-cpg: Update clock/reset definitions")
