    intel-vbtn: new driver for Intel Virtual Button

    This driver supports power button event in Intel Virtual Button currently.
    New Dell XPS 13 requires this driver for the power button.

    This driver is copied/modified from intel-hid.c

From Win 8.1+, BIOS might use the new way to handle the power button, it's called intel virtual button.
BIOS should switch to the new way while detecting there is a driver which supports it, but in this case, BIOS switches to the new way no matter there is a driver for it or not. And once this case happens, the power button emits the keyevent only after pressing it for 6 seconds.
To fix it, we need this driver to be loaded and emits the keyevent once it's pressed.

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 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!
