libata: make PMP support optional
Make PMP support optional by adding CONFIG_SATA_PMP and leaving out libata-pmp.c if it isn't set. PMP helpers return constant values if PMP support is not enabled and PMP declarations alias non-PMP counterparts. This makes the compiler to leave out PMP related part out and LLDs to use non-PMP counterparts automatically. Signed-off-by: Tejun Heo <htejun@gmail.com>
