xen/arm: Add macros to handle the MIDR

Add new macros to easily get different parts of the register and to
check if a given MIDR match a CPU model range. The latter will be really
useful to handle errata later.

The macros have been imported from the header
arch/arm64/include/asm/cputype.h in Linux v4.6-rc3.

Also remove MIDR_MASK which is unused.
