powerpc/powernv: Reserve additional space for IOV BAR, with m64_per_iov supported
M64 aperture size is limited on PHB3. When the IOV BAR is too big, this
will exceed the limitation and failed to be assigned.
Introduce a different mechanism based on the IOV BAR size:
- if IOV BAR size is smaller than 64MB, expand to total_pe
- if IOV BAR size is bigger than 64MB, roundup power2
