cortex_m: Restore fast register reads if no polling is needed

If the target is in a state where S_REGRDY polling is necessary (slow
clock, low power state...?), OpenOCD will continue to use the slow
path even if the condition is temporary and the target at a later
point would be capable of fast reads again.

Revert to fast reads if a full register dump can be made without need
for polling any of the registers; presumably it will succeed the next
time too.
