[MTD] Fix regression in RedBoot partition scanning

This fixes a regression introduced by the attempt to handle RedBoot FIS
tables which are smaller than an eraseblock, in commit
0b47d654089c5ce3f2ea26a4485db9bcead1e515

It moves the recalculation of the number of slots in the table to the
correct place, and improves the heuristic for when we think we need to
byte-swap what we read from the flash.

The read-while-load method of reading from OneNAND needs to allow
for the change of bufferRAM address at the boundary between the
two chips in a double density (DDP) device.

This patch teaches OneNAND to release processor in
read/write/erase cycles and let other processes proceed.
Also, remove buggi touch watchdog call which only hides
the problem instead of solving it.
