[SRU][Bionic][PULL] Amazon ENA driver update

[Kamal Mostafa]

Update Amazon ENA driver from latest upstream

BugLink: http://bugs.launchpad.net/bugs/1792044

These are all cherry-picks from mainline linux and linux-next (the single
SAUCE patch is a cherry-pick of just the ENA driver delta from a treewide
mainline commit).

Only the Amazon ENA driver is affected.

Note that some of these commits are already present in the linux-aws variant.
