ASoC: fsl_micfil: Add a flag to distinguish with different volume control types
[ Upstream commit da95e891dd5d5de6c5ebc010bd028a2e028de093 ]
On i.MX8MM the register of volume control has positive and negative
values. It is different from other platforms like i.MX8MP and i.MX93
which only have positive values. Add a volume_sx flag to use SX_TLV
volume control for this kind of platform. Use common TLV volume control
for other platforms.
Fixes: cdfa92eb90f5 ("ASoC: fsl_micfil: Correct the number of steps on SX controls")
