Subject: [PATCH v1 3/4] arm64: dts: qcom: qcs404: Add tsens controller

qcs404 has a single TSENS IP block with 10 sensors. The calibration data
is stored in an eeprom (qfprom) that is accessed through the nvmem
framework. We add the qfprom node to allow the tsens sensors to be
calibrated correctly.
