ipq806x: add ipq806x specific tsens driver

Current upstream driver doesnt fully support ipq806x devices
ipq806x has 11 sensors, the upstream one doesn't allow to check
sensors 0-4, only 5-10.

A specific driver for ipq806x has been found in Qualcomm SDK repo.

+Subject: [PATCH] ipq8064: tsens: Base tsens driver for IPQ8064
+
+Add TSENS driver template to support IPQ8064.
+This is a base file copied from tsens-8960.c

+ipq8064: tsens: TSENS driver support for IPQ8064
+
+Support for IPQ8064 tsens driver. The driver works
+with the thermal framework. The driver overrides the
+following fucntionalities:
+
+1. Get current temperature.
+2. Get/Set trip temperatures.
+3. Enabled/Disable trip points.
+4. ISR for threshold generated interrupt.
+5. Notify userspace when trip points are hit.

+Subject: [PATCH] ipq8064: tsens: Support for configurable interrupts
+
+Provide support for adding configurable high and
+configurable low trip temperatures. An interrupts is
+also triggerred when these trip points are hit. The
+interrupts can be activated or deactivated from sysfs.
+This functionality is made available only if
+CONFIG_THERMAL_WRITABLE_TRIPS is defined.

-Subject: [PATCH 63/69] ipq806x: clk: gcc: add tsens child node
-
-Thermal sensors in ipq806x are inside a Global clock controller.
-Add a child node into it to be used by the TSENS driver.
