[PATCH] ahci: convert to new probing mechanism and add hotplug support
Convert to new probing mechanism and add hotplug support by enabling
PORT_IRQ_PHYRDY, marking ehi for hotplug and scheduling EH on
CONNECT/PHYRDY interrupts.
Unfortunately, ahci cannot reliably wait for the first D2H FIS after
hotplug. It sometimes succeeds but times out more often than not, so
ATA_FLAG_SKIP_D2H_BSY is used.
This patch also fixes ahci_hardreset() such that D2H Register FIS RX
area is cleared before issuing COMRESET. Without this,
ata_busy_sleep() after COMRESET might prematually finish if the
previous TF contains DRDY && !BSY.
