devm_ioremap_resource does sanity checks on the given resource. No need to
duplicate this in the driver.

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

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.

The Marvell Dove SoC has a thermal sensor. Add a driver using the
thermal framework.
