hwmon: qpnp-adc: Support configurable pull-ups
VADC peripheral has internal support to select
configurable pull-ups through a configurable AMUX
100k and 150k pull-up. Clients who need the
configurable pull-up include PA_THERM's, XO_THERM's,
EMMC_THERM, MSM_THERM can select the appropriate
channel id to select the 100k/150k pull-up.
