Sachin Kamat 90c3194e47 Thermal: kirkwood: Remove redundant use of of_match_ptr
'kirkwood_thermal_id_table' is always compiled in and the driver
is dependent on OF. Hence use of of_match_ptr is unnecessary.

Wolfram Sang c28f692c6f drivers/thermal: don't check resource with devm_ioremap_resource
devm_ioremap_resource does sanity checks on the given resource. No need to
duplicate this in the driver.

Sachin Kamat 0f3913bd2d Thermal: kirkwood: Remove redundant platform_set_drvdata()
Commit 0998d06310 (device-core: Ensure drvdata = NULL when no
driver is bound) removes the need to set driver data field to
NULL.

Ezequiel Garcia 696b6075af thermal: kirkwood: 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

Ezequiel Garcia 02519d3397 thermal: kirkwood: Fix valid check for thermal register
The correct value is obtain by first shifting the register by the offset,
later applying the valid mask and finally invert the result.
This check was lacking an extra parenthesis to be strictly correct.

Sachin Kamat aa3b5d222d Thermal: kirkwood: 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.
