ACPI: thinkpad-acpi: update brightness sysfs interface support
Update the brightness sysfs interface (done through the backlight class) to
be in line with the rest of the thinkpad-acpi driver.
This renames the incorrect, un-obvious, and clash-prone name of "ibm" for
the backlight device to a much more fitting and descriptive
"thinkpad_screen". This is something I wanted to do for quite a while...
