[PULL][Zesty] arm64 fixes for zesty

[dann frazier]

Here's a set of miscellaneous arm64 changes for zesty. It includes
fixes (erratum/quirking) for the QDF2400 platform, a follow-up fix for
the previously merged VFIO backport, and a GICv3 ITS performance fix.

All are cherry picks from upstream, with minor backporting required
for the pl011 workaround.

The following changes since commit ba46da7c1cc57d83f6af66bfe8f10516151c7923:
