This patch adds hp-poll support to the following drivers.
* sata_nv (generic)
* sata_sis
* sata_svw
* sata_uli
* sata_via
* sata_vsc
All the above drivers currently don't support hotplug interrupts (H/W
restrictions or lack of doc/effort) and all hotplug operations should
be done via hp-poll; thus, ATA_FLAG_HP_POLLING is set for these
drivers.
