Daniel Mack fb60870f63 [ARM] pxa: add MFP_PULL_FLOAT 
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.
