clk: renesas: r9a07g044: Add ethernet clock sources
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).
