This series adds the Non-Volatile Memory Controller, which controls access to
the User Information Control Registers (UICR), Factory Information Control
Registers (FICR), and flash memory.

This is the last piece of microbit work needed to make basic programs like
Micropython "Hello world" work under QEMU.

Originally sent as part of Steffen's longer microbit device emulation series, I
extracted this and deferred it until later because cleanups were necessary:

 * Use memory_region_flush_rom_device() to dirty/invalidate memory [Peter]
   ^--- Paolo: I CCed you on this new memory API
 * Fix device-introspect-test segfault due to missing owner when initializing
   FICR and UICR memory regions [Peter]
 * Fix off-by-one assertion checks [Peter]
 * Fix missing whitespace at end of comment [Peter]
 * Clear UICR on reset - we'd need a block device for true non-volatility
   [Peter]
