ssb: SPROM: extract each core power info
We already extract some basic info but it's incomplete, reads info about the first core only. Used data structure doesn't allow easy adding of more cores. This patch adds new struct and array for storing power info. The plan is to: switch all extractors (including the ones using NVRAM) to new struct, switch drivers, then deprecate and finally drop old SSB fields.
