usb_amd_find_chipset_info() is used for chipset detection for several quirks. It is strange that its return value indicates the need for the PLL quirk, which means it is often ignored. This patch adds a function specifically for checking the PLL quirk like the other ones. Additionally, rename probe_result to something more appropriate.
