[SRU][PULL][aws/groovy] nitro_enclaves driver

[Kamal Mostafa]

BugLink: https://bugs.launchpad.net/bugs/1903087

Add the nitro_enclaves driver from mainline to linux-aws/{focal,bionic-5.4} and
linux-aws/{groovy,hirsute}. The driver is supplied by mainline commits [see
buglink], which are all clean cherry picks for groovy with a couple of trivial
backports for focal.

This [aws/groovy] pull req needs to be applied to linux-aws/groovy;
linux-aws/hirsute (currently a copy of groovy) will copy it from there.
