Subject[PATCH V3 2/4] thermal/drivers/qcom: Add new feat for soc without rpm
Date
From: Sricharan Ramabadhran <quic_srichara@quicinc.com>

In IPQ5018, Tsens IP doesn't have RPM. Hence the early init to
enable tsens would not be done. So add a flag for that in feat
and skip enable checks. Without this, tsens probe fails.
