Subject: [PATCH V2 4/4] arm64: dts: qcom: ipq5018: Add tsens node
IPQ5018 has tsens V1.0 IP with 4 sensors.
There is no RPM, so tsens has to be manually enabled. Adding the tsens
and nvmem node and IPQ5018 has 4 thermal sensors (zones). With the
critical temperature being 120'C and action is to reboot. Adding all
the 4 zones here.
Signed-off-by: Sricharan Ramabadhran <quic_srichara@...cinc.com>

[v2] Fixed node names, order and added qfprom cells for points
seperately to use the calibrate_common and squashed thermal_zone
nodes here
