thinkpad-acpi: let other subdrivers know backlight level range
Extract the backlight level range size detection from the brightness
subdriver, and allow the other subdrivers access to that information.
This also allows us to relocate some code to a more convenient place.
The moved code was largerly unmodified, except for the return type of
tpacpi_check_std_acpi_brightness_support(), which now is correctly
marked as returning "unsigned int", and and two cosmetic fixes to make
checkpatch.pl happy.
Fixes for the NVRAM polling mode for the brightness hotkeys will need
this.
