media: rzg2l-cru: Skip ICnMC configuration when ICnSVC is used

Browse source

When the CRU is configured to use ICnSVC for virtual channel mapping,
as on the RZ/{G3E, V2H/P} SoC, the ICnMC register must not be
programmed.

Return early after setting up ICnSVC to avoid overriding the ICnMC
register, which is not applicable in this mode.

This prevents unintended register programming when ICnSVC is enabled.
