xen/common: add ARM stub for the function memory_type_changed()

MTRR-related code is not available for the ARM architecture. Given
that the memory_type_changed() function would be called also from
common code, its invocation is currently ifdef'd out to be only
compiled in on an x86 machine. This commit adds an empty stub for ARM.
