pxa: Remove unused MFP LPM definition

MFP_LPM_INPUT snuck in some time ago as part of "[PATCH] pxa: better MFP low power state support for pxa25x/pxa27x", but went unused in the final revision of said patch. Using it on PXA3xx would cause an out-of-bounds access of mfpr_table[]. Let's remove it before someone gets hurt.
