This series enables general KVM support for AP-passthrough for Secure
Execution guests (PV-guests).

To enable AP inside PV-guests two things have to be done/considered:
	1) set corresponding flags in the Create Secure Configuration UVC if
     firmware supports AP for PV-guests (patch 3).
	2) enable/disable AP in PV-guests if the VMM wants this (patch 2).

since v2:
  - applied styling recommendations from Heiko

since v1:
  - PATCH 1: r-b from Claudio
  - PATCH 2: fixed formatting issues (Claudio)
  - PATCH 3: removed unnecessary checks (Claudio)
