>Description:
	FreeBSD ata driver doesn't know VIA CX700M2 chipset and it fallback
	to UDMA33 mode on boot.
	This patch introduces VIA CX700M2 to FreeBSD ata driver.
	I'm not sure this chipset has AHCI feature.
	http://www.via.com.tw/en/products/chipsets/c-series/cx700m/

	before:
	atapci0: <VIA ATA controller> port 0x1f0-0x1f7,0x3f6,0x170-0x177,0x376,0xff00-0xff0f at device 15.0 on pci0
	ad2: 152627MB <Hitachi HTE541616J9AT00 SB4OA75H> at ata1-master UDMA33

	after:
	atapci0: <VIA CX700M2 SATA300 controller> port 0x1f0-0x1f7,0x3f6,0x170-0x177,0x376,0xff00-0xff0f at device 15.0 on pci0
	ad2: 152627MB <Hitachi HTE541616J9AT00 SB4OA75H> at ata1-master UDMA100
	# HTE541616J9AT00 is an UDMA100 device.

	CX700 and CX700M are also not have been added to ata driver,
	but I don't know PCI IDs of these chipsets, sorry.
>How-To-Repeat:
	
>Fix:
patch to FreeBSD 6.3-RELEASE.
