Subject: [PATCH v2] allow xenfb initialization for hvm guests

There is no reasons why an HVM guest shouldn't be allowed to use xenfb.
As a matter of fact ARM guests, HVM from Linux POV, can use xenfb.
Given that no Xen toolstacks configure a xenfb backend for x86 HVM
guests, they are not affected.

Please note that at this time QEMU needs few outstanding fixes to
provide xenfb on ARM:
