There are tons of quirks for HD-audio and many of them are without model string, hence it's not trivial to apply the same quirk for a new device. This patch makes it easier: namely, the model string accepts a form as "XXXX:YYYY" (a pair of hex numbers of the subsystem-vendor and subsystem-device IDs), to specify the alias of PCI (or codec) SSID. e.g. passing model=1234:abcd would apply the quirk that matches with the given SSID 1234:abcd instead of the actual SSID.
