Subject: [PATCH v2] staging: kpc2000: Add dependency on MFD_CORE to kconfig symbol 'KPC2000'

The kpc2000 core makes calls against functions conditionally exported
upon selection of the kconfig symbol MFD_CORE. Therefore, the kpc2000
core depends upon the mfd_core, and that dependency must be tracked in
Kconfig to avoid potential build issues.

v2 changes
  - base patch on staging-linus
  - only add MFD_CORE dependency as the UIO dependency has already been
    handled by YueHaibing
