Jan Beulich c3c756bde3 x86/p2m: use large pages for MMIO mappings ...

When mapping large BARs (e.g. the frame buffer of a graphics card) the
overhead of establishing such mappings using only 4k pages has,
particularly after the XSA-125 fix, become unacceptable. Alter the
XEN_DOMCTL_memory_mapping semantics once again, so that there's no
longer a fixed amount of guest frames that represents the upper limit
of what a single invocation can map. Instead bound execution time by
limiting the number of iterations (regardless of page size).
