[PATCH 0/2] ArmVirtPkg, OvmfPkg: connect Virtio RNG devices again

[Laszlo Ersek <lersek@redhat.com>]

Repo:   https://github.com/lersek/edk2.git
Branch: connect_vrng_bz1579518

This is a fix for another regression from the March 2018 series

  [edk2] [PATCH 0/6] OvmfPkg, ArmVirtQemu: leaner platform BDS policy
                     for connecting devices

Turns out EfiBootManagerConnectAll() used to connect devices one doesn't
really think about every day. I stumbled upon this when an aarch64 guest
kernel printed

> EFI stub: EFI_RNG_PROTOCOL unavailable, no randomness supplied

whereas I had just looked at the domain XML and seen the virtio-rng
device model in it.

Tested extensively as described in
<https://bugzilla.redhat.com/show_bug.cgi?id=1579518#c0> and
<https://bugzilla.redhat.com/show_bug.cgi?id=1579518#c2>.
