This applies a SND_PCI_QUIRK(...) to the TongFang PHxTxX1 barebone. This fixes the issue of the internal Microphone not working after booting another OS. When booting a certain another OS this barebone keeps some coeff settings even after a cold shutdown. These coeffs prevent the microphone detection from working in Linux, making the Laptop think that there is always an external microphone plugged-in and therefore preventing the use of the internal one. The relevant indexes and values where gathered by naively diff-ing and reading a working and a non-working coeff dump.
