clk: renesas: rzg2l: Add helper for mod clock enable/disable

Refactor rzg2l_mod_clock_endisable() by extracting its logic into a new
helper function rzg2l_mod_clock_endisable_helper(), which accepts an
additional set_mstop_state boolean parameter.  This allows callers to
control whether the module stop state is updated alongside the clock
enable/disable operation.  No functional change for existing callers.
