clk: renesas: rzv2h: Add fixed-factor module clocks with status reporting

Add support for fixed-factor module clocks that can report their enable
status through the module status monitor. Introduce a new clock type,
CLK_TYPE_FF_MOD_STATUS, and define the associated structure,
rzv2h_ff_mod_status_clk, to manage these clocks.

Implement the .is_enabled callback by reading the module status register
using monitor index and bit definitions. Provide a helper macro,
DEF_FIXED_MOD_STATUS, to simplify the definition of such clocks.
