Almost all of the functions defined in mptbase.{c,h} are only ever
called with sleepFlag == CAN_SLEEP, so this parameter is unnecessary.
Remove it.
I implemented this by fixing up a single function at a time to make sure
that each was being called from a non-atomic context.
One exception is the function WaitForDoorbellAck, which does use the
sleepFlag argument, so that one was left in place.
