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. Signed-off-by: Tejun Heo <htejun@gmail.com>
