Prepare for support of future MediaTek SoCs by renaming struct mtk_scp_domain to struct mtk_scpsys.
Upcoming SoCs require additional per-domain runtime data obtained from Device Tree. To keep the domain_data description in soc_data static const, a new wrapper structure will be introduced to combine the immutable domain_data description with the runtime data. The natural name for that wrapper is struct mtk_scp_domain, so free that name by renaming the existing runtime state structure to struct mtk_scpsys. Update the MT7623 and MT7629 drivers accordingly. No functional change intended.
