Panels using a PWM-controlled backlight source without an do not have a
standard way to communicate their valid PWM ranges.
On x86 the ranges are read from ACPI through driver-specific tables.
The built-in ranges are not necessarily correct, or may grow stale if an
older device can be retrofitted with newer panels.

Add a quirk infrastructure with which the valid backlight ranges can be
maintained as part of the kernel.
