[linux-yocto] [PATCH 07/16] mfd/intel_soc_pmic_bxtwc: add Intel BXT WhiskeyCove PMIC ADC thermal channel-zone

[Nilesh Bacchewar]

This changes adds the mapping of Intel BXT WhiskeyCove PMIC ADC channel
to thermal zone. This mapping is used in the pmic thermal driver to
notify the thermal zone with the pmic adc channel alert interrupts.
