Subject: [PATCH V8 02/12] soc: mediatek: add header for mediatek SIP interface

Add a header to collect SIPs and add one SIP call to initialize power
management hardware for the SIP interface defined to access the SPM
handling vcore voltage and ddr rate changes on mt8183 (and most likely
later socs).
