libata: separate PMP support code from core code
Most of PMP support code is already in libata-pmp.c. All that are in
libata-core.c are sata_pmp_port_ops and EXPORTs. Move them to
libata-pmp.c. Also, collect PMP related prototypes and declarations
in header files and move them right above of SFF stuff.
This change is to make PMP support optional.
