ALSA: hda - Use position_fix=3 as default for AMD chipsets
AMD chipsets often behave pretty badly regarding the DMA position reporting. It results in the bad quality audio recording. Using position_fix=3 works well in general for them, so let's enable it as default for AMD. Signed-off-by: Takashi Iwai <tiwai@suse.de>
