Power button does not work on Latitude 7480

Bug Description

When power button is pressed, a menu should pop up or the system should enter suspend; however, neither occurs.

SRU Justification:

Impact: Without the fix certain keys (like the power button) will not work on laptops using 5 button arrays with the intel-hid driver.

Fix: Changes backported from upstream which (based on capability bit) will selectively enable 5 button support for the intel-hid driver. Regression potential should be low due to the fencing with capability and requiring support for a special call to enable the feature.

Testcase: Power button working on the Latitude 7480 (also has been regression tested on a platform without 5 button support).

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-xenial' to 'verification-done-xenial'. If the problem still exists, change the tag 'verification-needed-xenial' to 'verification-failed-xenial'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
