Xenial linux-gcp lacks GVE suspend support

Bug description:
SRU Justification
[Impact]
Google would like suspend support in all kernels. This ticket covers suspend
support for the GVE driver going back to Xenial.
[Fix]
Backport 974365e51861 ("gve: Implement suspend/resume/shutdown") to -gcp
kernels missing it.
[Test Plan]
Suspend and resume a Xenial instance with a GVNIC and SCSI disk (NVMe suspend
is not yet working). In an unpatched kernel, the GVE driver times out and gets
reset by a net device watchdog. In the patched kernel, networking resumes
quickly after resuming without a watchdog timer.
[Regression Potential]
Since the added suspend/resume functionality should only happen when
suspending and resuming, and suspending in previous kernels ended up crashing
the driver anyway, a regression is unlikely to be more severe than the
previously broken functionality.
