[0/2] hw/arm/virt: Handle HVF in finalize_gic_version()

Message

The finalize_gic_version() function tries to determine which GIC version
the current accelerator / host combination supports. During the initial
HVF porting efforts, I didn't realize that I also had to touch this
function. Then Zenghui brought up this function as reply to my HVF GICv3
enablement patch - and boy it is a mess.

This patch set cleans up all of the GIC finalization so that we can
easily plug HVF in and also hopefully will have a better time extending
it in the future. As second step, it explicitly adds HVF support and
fails loudly for any unsupported accelerators.

v1 -> v2:

  - Leave VIRT_GIC_VERSION defines intact, we need them for MADT generation
  - Include TCG header for tcg_enabled()
