Philippe, Peter,
Thank you for the comments. I am not even sure what the semantics of
putting a breakpoint or watchpoint
on device regions are supposed to be. I would imagine it is
architecture-specific as to whether this is even allowed.
It appears for example, that armv8-a allows watchpoint

Writes from GDB to memory-mapped IO regions are currently silently
dropped. cpu_memory_rw_debug() calls address_space_write_rom(), which
calls address_space_write_rom_internal(), which ignores all non-ram/rom

Add a check for MMIO regions and direct those to address_space_rw()
instead.
