Stop abusing xpt_periph in random plases that really have no periph related to CCB, for example, bus scanning. NULL value is fine in such cases and it is correctly logged in debug messages as "noperiph". If at some point we need some real XPT periphs (alike to pmpX now), quite likely they will be per-bus, and not a single global instance as xpt_periph now.
