[PATCH v2 15/28] hw/display: mark bochs, ramfb and VGA as secure

["Daniel P. Berrangé" <berrange@redhat.com>]

Most of the display adapters are emulating old hardware which is not
relevant to virtualization use cases.

The clear exceptions are the generic, simple devices that should be
considered secure: Bochs, RAMFB, VGA (PCI, not MMIO / ISA).
