thermal: consistently use int for temperatures
...
The thermal code uses int, long and unsigned long for temperatures
in different places.
Using an unsigned type limits the thermal framework to positive
temperatures without need. Also several drivers currently will report
temperatures near UINT_MAX for temperatures below 0°C. This will probably
immediately shut the machine down due to overtemperature if started below
0°C.
'long' is 64bit on several architectures. This is not needed since INT_MAX °mC
is above the melting point of all known materials.
Consistently use a plain 'int' for temperatures throughout the thermal code and
the drivers. This only changes the places in the drivers where the temperature
is passed around as pointer, when drivers internally use another type this is
not changed.

thermal: drop owner assignment from platform_drivers
...
A platform_driver does not need to set an owner, it will be populated by the

Thermal: dove: Remove redundant use of of_match_ptr
...
'dove_thermal_id_table' is always compiled in and the driver
is dependent on OF. Hence use of of_match_ptr is unnecessary.

thermal: dove: Fix thermal sensor formula
...
The currently formula has been taken from the 88AP510 SoC datasheet,
which is not exactly correct. The correct value for the temperature
in Celcius of the sensor present in this SoC is:
Celsius = (322-reg)/1.3625

Thermal: dove: Convert to devm_ioremap_resource()
...
Use the newly introduced devm_ioremap_resource() instead of
devm_request_and_ioremap() which provides more consistent error handling.
devm_ioremap_resource() provides its own error messages; so all explicit
error messages can be removed from the failure code paths.
