mfd: intel-m10-bmc: Change staging size to a variable
The secure update driver does a sanity-check of the image size in comparison to the size of the staging area in FLASH. Instead of hard-wiring M10BMC_STAGING_SIZE, move the staging size to the m10bmc_csr_map structure to make the size assignment more flexible.
