pata_via: add VX800 flag; add function for fixing h/w bugs

Add flag VIA_SATA_PATA for vx800, VX800 uses the same
chipset(0x0581/0x5324) as CX700, which has 1 PATA channel(Master/Slave)
and 1 SATA channel(Master/Slave) Add function <via_ata_tf_load>.  This is
to fix the internal bug of VIA chipsets, which will reset the device
register after changing the IEN bit in CTL register
