libata: clear SError after link resume
SError used to be cleared in ->postreset. This has small hotplug race
condition. If a device is plugged in after reset is complete but
postreset hasn't run yet, its hotplug event gets lost when SError is
cleared. This patch makes sata_link_resume() clear SError. This
kills the race condition and makes a lot of sense as some PMP and host
PHYs don't work properly without SError cleared.
This change makes sata_pmp_std_{pre|post}_reset()'s unnecessary as
they become identical to ata_std counterparts. It also simplifies
sata_pmp_hardreset() and ahci_vt8251_hardreset().
