[libata sata_nv] cleanups: convert #defines to enums; remove in-file history

 *  NV-specific details such as register offsets, SATA phy location,

 *  hotplug info, etc.

 *

 *  0.10

 *     - Fixed spurious interrupts issue seen with the Maxtor 6H500F0 500GB

 *       drive.  Also made the check_hotplug() callbacks return whether there

 *       was a hotplug interrupt or not.  This was not the source of the

 *       spurious interrupts, but is the right thing to do anyway.

 *

 *  0.09

 *     - Fixed bug introduced by 0.08's MCP51 and MCP55 support.

 *

 *  0.08

 *     - Added support for MCP51 and MCP55.

 *

 *  0.07

 *     - Added support for RAID class code.

 *

 *  0.06

 *     - Added generic SATA support by using a pci_device_id that filters on

 *       the IDE storage class code.

 *

 *  0.03

 *     - Fixed a bug where the hotplug handlers for non-CK804/MCP04 were using

 *       mmio_base, which is only set for the CK804/MCP04 case.

 *

 *  0.02

 *     - Added support for CK804 SATA controller.

 *

 *  0.01

 *     - Initial revision.
