[ Upstream commit b0217519236924f77a8382b4004e43ef8fd0dcbb ]

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.
