[ARM] pxa: remove un-used pxa3xx_mfp_set_xxx() functions

Browse Source 
pxa3xx_mfp_set_xxx() functions are originally provided for overwriting
MFP configurations performed by pxa3xx_mfp_config(), the usage of such
a dirtry trick is not recommended, since there is currently no user of
these functions, they are safely removed
