The driver supports qemu machine types 'pc' and 'q35'. This patch adds some helper functions to manage the bitmasks. The implemented features depend on both OVMF build configuration and qemu VM configuration. For q35 a single security feature is supported and checked: In SMM-enabled builds the driver will verify smram is properly locked. That test should never fail.
