x86/Xen: tidy xen-head.S
First of all move PV-only ELF notes inside the XEN_PV conditional; note
that
- HV_START_LOW is dropped altogether, as it was meaningful for 32-bit PV
only,
- the 32-bit instance of VIRT_BASE is dropped, as it would be dead code
once inside the conditional,
- while PADDR_OFFSET is not exactly unused for PVH, it defaults to zero
there, and the hypervisor (or tool stack) complains if it is present
but VIRT_BASE isn't.
Then have the "supported features" note actually report reality: All
three of the features there are supported and/or applicable only in
certain cases.
