ata: parport_pc: add 16-bit and 8-bit fast EPP transfer flags

Browse Source 
PARPORT_EPP_FAST flag currently uses 32-bit I/O port access for data
read/write (insl/outsl).
Add PARPORT_EPP_FAST_16 and PARPORT_EPP_FAST_8 that use insw/outsw
and insb/outsb (and PARPORT_EPP_FAST_32 as alias for PARPORT_EPP_FAST).
