Philippe Mathieu-Daudé 3ab6fdc91b softmmu/physmem: Introduce MemTxAttrs::memory field and MEMTX_ACCESS_ERROR 
Add the 'memory' bit to the memory attributes to restrict bus
controller accesses to memories.

Introduce flatview_access_allowed() to check bus permission
before running any bus transaction.

Have read/write accessors return MEMTX_ACCESS_ERROR if an access is
restricted.

There is no change for the default case where 'memory' is not set.
