992e2ed0ab thermal: Constify struct thermal_zone_device_ops
'struct thermal_zone_device_ops' are not modified in these drivers.

Constifying these structures moves some data to a read-only section, so
increases overall security, especially when the structure holds some
function pointers.

On a x86_64, with allmodconfig, as an example:
Before:
======
   text	   data	    bss	    dec	    hex	filename
  28116	   5168	    128	  33412	   8284	drivers/thermal/armada_thermal.o

After:
=====
   text	   data	    bss	    dec	    hex	filename
  28244	   5040	    128	  33412	   8284	drivers/thermal/armada_thermal.o

bccdbba51a thermal: rcar_gen3: Reuse logic to read fuses on Gen3 and Gen4
The hardware calibration is fused on some, but not all, Gen3 and Gen4
boards. The calibrations values are the same on both generations but
located at different register offsets.

Instead of having duplicated logic to read the and store the values
create structure to hold the register parameters and have a common
function do the reading.

dd64594ca2 thermal: Switch back to struct platform_driver::remove()
After commit 0edb555a65 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/thermal to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

On the way make a few whitespace changes to make indention consistent.

79f194dd54 thermal: trip: Get rid of thermal_zone_get_num_trips()
The only existing caller of thermal_zone_get_num_trips(), which is
rcar_gen3_thermal_probe(), uses this function to put the number of
trip points into a kernel log message, but this information is also
available from the thermal sysfs interface.

For this reason, remove the thermal_zone_get_num_trips() call from
rcar_gen3_thermal_probe() and drop the former altogether.
