Don't write SCKDIV when flashing
...
The target may have already configured its clock to run at a higher frequency and would have set SCKDIV and other dividers at that time. Don't restore the SCKDIV to its default or the flash interface may run too fast and programming will fail.
Otherwise, the default value is fine and there is no need to write SCKDIV.

Fix bug with slow targets.
...
Halting didn't work right in slow targets, because some code assumed the
register cache is valid before it was guaranteed to be.
Also made dbus_busy_delay and interrupt_high_delay grow faster, so that
on slow targets it takes less time to learn the correct values.
