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.

Xu Yilun, Peter,
Do you require a pull-request from an immutable branch for this?

No need. The patchset could all be applied to mfd branch.
