refactor(mediatek): smc registration services

To modularize SMC handler, provide macro function in mtk_sip_svc.h.
Drivers register SMC name with value in mtk_sip_def.h, and bind the SMC
handler with the SMC ID by calling DECLARE_SMC_HANDLER macro.

MTK_SIP_SMC_FROM_BL33_TABLE expand the SMC table as switch-case table
statically. DECLARE_SMC_HANDLER wrap SMC handlers with a structure and
put in a section.
During cold boot initialization, in MTK_EARLY_PLAT_INIT level parse the
section to assign each handler with an index. Each SMC request can be
identified with switch-case and take the index to call into
corresponding SMC handler.
