nv50: modified FP attribute loading

VP outputs that should be loadable in the FP are mapped to
interpolant indices by HPOS, COL0 etc.; of course HPOS is
always written, so the highest byte of 1988 is a bitmask that
selects which components of HPOS are used for interpolants,
i.e. the FP inputs in COL0 start at index POPCNT(1988[24:28]).
