Roger Pau Monné 5f640b6213 x86/dom0: correctly set the maximum ->iomem_caps bound for PVH

The logic in dom0_setup_permissions() sets the maximum bound in
->iomem_caps unconditionally using paddr_bits, which is not correct for HVM
based domains.  Instead use domain_max_paddr_bits() to get the correct
maximum paddr bits for each possible domain type.

Switch to using PFN_DOWN() instead of PAGE_SHIFT, as that's shorter.
