--------------------------------

[ Upstream commit d431dfb7 ]

It turns out that there is a WMI object which controls the PWM2 device
used for the keyboard backlight and that WMI object also provides some
other useful functionality.

The upcoming lenovo-yogabook-wmi driver will offer both backlight
control and the other functionality, so there no longer is a need
to have the lpss-pwm driver binding to PWM2 for backlight control;
and this is now actually undesirable because this will cause both
the WMI code and the lpss-pwm driver to poke at the same PWM
controller.

Drop the always-present quirk for the PWM2 ACPI-device, so that the
 lpss-pwm controller will no longer bind to it.
