[linux-aws-bionic][PULL] xen hibernation support for linux-aws

[Kamal Mostafa]

BugLink: http://bugs.launchpad.net/bugs/1804533

AWS-specific xen hibernation support (as is already supported in linux-aws
Xenial and Trusty) has been ported to linux-aws Bionic by the Amazon team.

This patch set passes simple hibernation smoke-testing on an instance.
