Add support for generic electronic privacy screen properties, that
can be added by systems that have an integrated EPS.
Changes in v2 (Hans de Goede)
- Create 2 properties, "privacy-screen sw-state" and
"privacy-screen hw-state", to deal with devices w
driver for these
other devices to register themselves as a privacy-screen provider; and
allowing the drm/kms code to get a privacy-screen provider associated
with a specific GPU/connector combo.

This means that initrd generation tools will need to be updated to
include thinkpad_acpi when the i915 driver is added to the initrd.
Without this the loading of the i915 driver will be delayed to after
the switch to real rootfs.

Hi All,
Here is hopefully the last version of this series, as everything seems
to be ready for merging this now.
The only difference from v9 is correcting some mistakes in the commit-msg of:

Honoring the VBT specified PWM frequency will also hopefully fix the
various bug reports which we have received about users perceiving the
