ipq806x: add ipq806x specific tsens driver

Browse Source 
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.
