Philippe Mathieu-Daudé 24ce762df7 hw/char/mchp_pfsoc_mmuart: Use a MemoryRegion container 
Our device have 2 different I/O regions:
- a 16550 UART mapped for 32-bit accesses
- 13 extra registers

Instead of mapping each region on the main bus, introduce
a container, map the 2 devices regions on the container,
and map the container on the main bus.

Before:
