thermal: broadcom: Add Stingray thermal driver

Stingray SoC has six temperature sensor and those are
configured, controlled and accessed to read temperature
and update in DDR memory using m0 firmware.
All six sensors has been given 4 bytes of memory in DDR
to write temperature in millivolts.

This thermal driver read temperature values from DDR
because no direct access to sensors.
Like this all temparature sensors are monitored and
trips at critical temperature.

If driver can't handle thermal runaways because of
any unknown reason, then firmware in m0 Processor
will handle.

thermal: add brcmstb AVS TMON driver

The AVS TMON core provides temperature readings, a pair of configurable
high- and low-temperature threshold interrupts, and an emergency
over-temperature chip reset. The driver utilizes the first two to
provide temperature readings and high-temperature notifications to
applications. The over-temperature reset is not exposed to
applications; this reset threshold is critical to the system and should
be set with care within the bootloader.

Applications may choose to utilize the notification mechanism, the
temperature reading mechanism (e.g., through polling), or both.
