Subject: [PATCH 07/16] ASoC: codecs: wcd938x: fix kcontrol max values

set "HPH Type" Kcontrol max value of WCD_MBHC_HPH_STEREO instead of UINT_MAX.
set "HPHL/R Impedance" Kcontrols max value to INT_MAX instead of UINT_MAX as
max field is integer type.

Without this patch amixer for these controls will show -1 as max value to userspace.

Fixes: bcee7ed09b8e ("ASoC: codecs: wcd938x: add Multi Button Headset Control support")
