[ARM] pxa/spitz: convert to use new MFP API

Original patch from Dmitry Baryshkov's initial scoop gpio conversion
work at http://git.infradead.org/users/dbaryshkov/zaurus-2.6.git.

TODO: figure out the MFP configuration of the SSP2 which looks like
to be already configured by the boot loader, though.
