clk: renesas: rzg2l: Re-enable critical module clocks during resume

Browse source

After a suspend/resume cycle, critical module clocks (CLK_IS_CRITICAL)
may be left disabled as there is no owning driver to restore them,
unlike regular clocks.
Add rzg2l_mod_enable_crit_clock_init_mstop() which walks all module
clocks on resume, re-enables any critical clock found disabled, and then
restores the MSTOP state for clocks that have one via the existing
helper.  This replaces the direct call to rzg2l_mod_clock_init_mstop()
in rzg2l_cpg_resume(), preserving the correct clock-before-MSTOP restore
ordering.
