clk: renesas: r9a09g057: Add support for PLLVDO, CRU clocks, and resets

Add support for the PLLVDO clock and its related CRU clocks and reset
entries in the r9a09g057 CPG driver. Introduce `CLK_PLLVDO` and associated
clocks like `CLK_PLLVDO_CRU0`, `CLK_PLLVDO_CRU1`, `CLK_PLLVDO_CRU2`, and
`CLK_PLLVDO_CRU3`, along with their corresponding dividers.
