ARM: dts: msm: Update ADC configuration for wlan_therm

Browse Source 
wlan_therm has a 100k pullup connected to it on the board for
all platforms other than SG, so update VADC and ADC_TM
configurations for it accordingly to ensure it gives accurate readings.
While at it, also add additional thermal trip required for all
thermal zones.
