Subject: [PATCH 0/2] Remove Xen PVH dependency on PCI

A Xen PVH domain doesn't have a PCI bus or devices, so it doesn't need
PCI support built in.  Currently, XEN_PVH depends on XEN_PVHVM which
depends on PCI.

The first patch introduces XEN_PVHVM_GUEST as a toplevel item and
changes XEN_PVHVM to a hidden variable.  This allows XEN_PVH to depend
on XEN_PVHVM without PCI while XEN_PVHVM_GUEST depends on PCI.

The second patch moves XEN_512GB to clean up the option nesting.
