clk: renesas: rzg2l-cpg: Add support for RZ/V2L SoC

The clock structure for RZ/V2L is almost identical to the RZ/G2L SoC.
The only difference being that RZ/V2L has additional registers to
control clocks and resets for the DRP-AI block.

Reuse r9a07g044-cpg.c, as the clock IDs and reset IDs are the same
between RZ/G2L and RZ/V2L, and add a separate r9a07g054_cpg_info to take
care of the DRP-AI clocks/resets.
