armv7m: Make bitband device take the address space to access
Instead of the bitband device doing a cpu_physical_memory_read/write,
make it take a MemoryRegion which specifies where it should be
accessing, and use address_space_read/write to access the
corresponding AddressSpace.
Since this entails pretty much a rewrite, convert away from
old_mmio in the process.
