Both intel-hid and intel-vbtn set a wakeup_mode flag causing them
to behave in a special way during system suspend and while suspended
in their "prepare" PM callbacks and clear it in their "resume" PM
callbacks.  That may cause the wakeup_mode flag to remain set after
a system suspend failure (if some other driver's "suspend" callback
returns an error before the "suspend" callback of either intel-hid
or intel-vbtn is invoked).

After commit 10a08fd6 ("ACPI: PM: Set up EC GPE for system wakeup
from drivers that need it") that also affects the "wakeup mask" bit
of the EC GPE, which may not be cleared after a failing system
suspend.

Fix this issue by adding "complete" PM callbacks to intel-hid and
intel-vbtn to clear the wakeup_mode flag and the "wakeup mask" bit
of the EC GPE if they have not been cleared earlier.
