Add common master API to adapt voltage
We start by setting the voltage in prepare_flash_access() and, if we
were told to probe for a specific chip, before the probing. For now,
we leave the programmer driver's default voltage during the probing,
otherwise.
Once the probing is more bus centric, we can implement a more elabo-
rate scheme. For instance, we can probe at the lowest voltage first
and only increase it if there was no response at all.
