[PATCH] ahci: fix notification handling

Asynchronous notification on ICH9 didn't work because it didn't write AN FIS into the RX area - it only updates SNotification. Also, snooping SDB_FIS RX area is racy against further SDB FIS receptions. Let sata_async_notification() determine using SNTF if it's available and snoop RX area iff SNTF

[PATCH 3/3] libata: use ata_exec_internal() for PMP register access

PMP registers used to be accessed with dedicated accessors -pmp_read and -pmp_write. During reset, those callbacks are called with the port frozen so they should be able to run without depending on interrupt delivery. To achieve this, they were implemented polling. However, as resetting the
