Roger Pau Monné a8f2f559f3 xen: unify gnttab initialization for PVHVM and PVH 
Switch the initialization of gnttab to use an unused physical memory
range for both PVHVM and PVH.

In the past PVHVM was using the xenpci BAR, but there's no reason to
do that, and in fact FreeBSD was probably doing it because it was the
way it was done in Windows, were drivers cannot probably request for
unused physical memory ranges, but it was never enforced in the
hypervisor.

Sponsored by: Citrix Systems R&D
Approved by: gibbs

xen/gnttab.c:
 - Allocate contiguous physical memory for grant table frames for both
   PVHVM and PVH.
 - Since gnttab is not a device, use the xenpv device in order to
   request for this allocation.

dev/xen/xenpci/xenpcivar.h:
dev/xen/xenpci/xenpci.c:
 - Remove the now unused xenpci_alloc_space and xenpci_alloc_space_int
   functions.

xen/gnttab.h:
 - Change the prototype of gnttab_init and gnttab_resume, that now
   takes a device_t parameter.

dev/xen/control/control.c:
x86/xen/xenpv.c:
 - Changes to accomodate the new prototype of gnttab_init and
   gnttab_resume.
