mfd: intel-m10-bmc: Move m10bmc_sys_read() away from header

Browse Source 
Move m10bmc_sys_read() out from the header to prepare it for adding
more code into the function which would make it too large to be a
static inline any more.

While at it, replace the vague wording in function comment with more
precise statements.
