ASoC: wcd-mbhc: Remove max impedance limit for lineout detection

Bläddra i källkod 
Max limit of 60k ohms was set for cable to be detected as lineout
to fix headset detected as lineout issue on legacy targets.
This was because of large impedance detected for headset.
This is not applicable for adc based targets as headset is
detected based on mic adc voltage. Remove max impedance limit for
lineout detection.
