[ALSA] oxygen: revert SPI clock frequency change for AK4396/WM8785
While the AK4396 and WM8785 datasheets say that the SPI clock cycle length must be at least 200 ns, 320 ns seems not to work reliably with the controller, so we better use 160 ns. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Jaroslav Kysela <perex@perex.cz>
