The thermal zone device structure is exposed to the different drivers
and obviously they access the internals while that should be
restricted to the core thermal code.
In order to self-encapsulate the thermal core code, we need to prevent
the drivers accessing directly the thermal zone structure and provide
accessor functions to deal with.
Use the devdata accessor introduced in the previous patch.
No functional changes intended.

The thermal OF code has a new API allowing to migrate the OF
initialization to a simpler approach. The ops are no longer device
tree specific and are the generic ones provided by the core code.
Convert the ops to the thermal_zone_device_ops format and use the new
API to register the thermal zone with these generic ops.

platform_get_resource() may return NULL, add proper check to
avoid potential NULL dereferencing.

Unlike DT framework, thermal-zones and its parameters can't be parsed
using ACPI framework. So that ACPI support is removed in this 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.
