Since mfpr_mmio_base[0] is not always valid on later SoCs,
fixed mpfr_sync() to read back from valid mfp offset always.

There is currently an uncovered case for MFP configuration on PXAs which
is selected by setting the PULL_SEL bit but none of the PULL{UP,DOWN}_EN
bits. This case is needed to explicitly let pins float, even if the
selected alternate function would default to a configuration with a pull
resistor enabled.
