ASoC: fsl_micfil: Add a flag to distinguish with different volume control types

Browse Source 
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.
