Subject: [PATCH v3 5/5] thermal/drivers/tsens: Add IPQ5332 support

IPQ5332 uses tsens v2.3.3 IP and it is having combined interrupt.
It does not have RPM and kernel needs to take care of sensor
enablement, calibration. Hence introduced new feature_config,
ops and data for IPQ5332.

Signed-off-by: Praveenkumar I <quic_ipkumar@...cinc.com>

[v3]:
	No changes.
[v2]:
	Added tsens_features for ipq5332 with VER_2_X_NO_RPM. Used
	hw_ids to mention the available sensors. Dropped v2 in
	ops_ipq5332.
