Antonio Borneo 5dc5ed5714 target/cortex_a: use aligned accesses for read/write cpu memory slow 
Armv7a is able to read and write memory at un-aligned address, but
only when bit SCTLR.A (Alignment check enable) is zero and the
address belongs to a memory space with attribute "Normal" (see [1]
chapter A3.2.1 "Unaligned data access"). In all the other cases
the memory access will trigger an alignment fault data abort
exception.
Memory attributes are explained in [1] chapter A3.5 "Memory types
and attributes and the memory order model".

Disabling the MMU cause a change in memory attribute, as explained
in [1] chapter B3.2 "The effects of disabling MMUs on VMSA
behavior".
This can cause several issues. e.g. a SW breakpoint on un-aligned
4-byte Thumb instruction, set when MMU is on, can be impossible to
remove when MMU turns off.

While is possible to check all the possible conditions before an
un-aligned memory access, it's clearly more maintainable to skip
such complexity and only perform aligned accesses.

Check the alignment and eventually modify the data size before
calling the functions cortex_a_{read,write}_cpu_memory_slow().
Change the comment in the two functions above to comply with the
new behaviour.

    and ARMv7-R edition"
