While in the end Tomasz'es problem description in the thread starting at
http://lists.xenproject.org/archives/html/xen-devel/2014-05/msg01902.html
turned out to not be BAR assignment related, looking into it nevertheless
revealed a couple of issues with hvmloader's handling of memory types
here.

1: also cover PCI MMIO ranges above 4G with UC MTRR ranges
2: PA range 0xfc000000-0xffffffff should be UC
