Huang Rui 02c123ee99 usb: ohci: use amd_chipset_type to filter for SB800 prefetch
Commit "usb: pci-quirks: refactor AMD quirk to abstract AMD chipset types"
introduced a new AMD chipset type to filter AMD platforms with different
chipsets.

According to a recent thread [1], this patch updates SB800 prefetch routine
in AMD PLL quirk. And make it use the new chipset type to represent SB800
generation.
