 Log Message:
 viaide(4): Improve VT8251 integrated SATA controller support in IDE/RAID modes.
 
 Use via_chip_map() to attach this controller in IDE and RAID modes, similarly
 to VX800. This allows drives to be identified and attached successfully on all
 four ports (two channels with master/slave ports).
 
 Switch channel setup to sata_setup_channel(), replacing via_setup_channel().
 This avoids writes to the 0x50 register, which is only relevant for IDE
 controllers. Writes to SATA controller registers caused drives on the IDE
 controller (0x0571) to fail to attach. Apply this fix also to VX900 and VT8261.
 
 Rename VT8237R_SATA to VT8251_SATA (0x3349 is not used for VT8237R, AFAIK).
 This PCI ID is used in RAID mode on newer (CE) chipset revision and in all
 modes (IDE/RAID/AHCI) on older revision.
 Add the 0x5287 PCI ID, used in IDE mode on newer (CE) chipset revision.
 Rename VT8251_SATA to VT8251_AHCI (0x6287 is used only in AHCI mode).
 Add VT8251_AHCI to the ahcisata(4) quirk list, same as VT8251_SATA.

 Should fix and close PR kern/37517.
 
 Tested on Asus A8V-VM (CD) and MSI MS-7318 (CE) motherboards.
