In function cortex_a_wait_dscr_bits() the last read on dscr gets
ignored in case of timeout, even if it finally provides the value
that would trigger a successful return.
Check the returned value before testing the timeout.
Also, print a message on failure reading dscr.

Depending on adapter speed, the function cortex_a_poll() can take
time to execute and can complete successfully when the timeout is
already expired. Checking the timeout at function return causes a
timeout error while that could be avoided.
Check the target status at cortex_a_poll() return, before checking
for the timeout.

Plus, it is going to be obsoleted by the HW thread pseudo RTOS.
Consolidate in smp.c a single instance of the command. This will
simplify both obsoleting it and adding it to cortex_m, whatever
change comes first.

Seams over-engineered having two separate commands to turn SMP
on/off. Plus it is missing the possibility to dump the current
status of SMP and would be weird adding an additional command
for it. Moreover, such commands are replicated in few targets so
it would make sense centralizing them.
- Deprecate the commands "smp_on" and "smp_off".
- Add a new command "smp" that accepts optional parameters
"[on|off]" and prints the SMP status when run without
parameters. This replaces the two commands above.
- Put the deprecated and the new command handlers in smp.c
- Update the documentation, except for mips_m4k, since it is not
available yet.
- Promote the macro foreach_smp_target to global context and use
it where possible.
