Peter Maydell f68d881c9b 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.

Peter Maydell 618119c2d3 armv7m: Make ARMv7M object take memory region link 
Make the ARMv7M object take a memory region link which it uses
to wire up the bitband rather than having them always put
themselves in the system address space.

Peter Maydell 56b7c66f49 armv7m: QOMify the armv7m container 
Create a proper QOM object for the armv7m container, which
holds the CPU, the NVIC and the bitband regions.
