* Configure the IOMD to give the appropriate timings for the transfer

*
* We have the following IOMD DMA modes to choose from:
*
* Type Active Recovery Cycle
* A 250 (250) 312 (550) 562 (800)
* B 187 250 437
* C 125 (125) 125 (375) 250 (500)
* D 62 125 187
*
* (figures in brackets are actual measured timings)
*
* However, we also need to take care of the read/write active and
* recovery timings:
*
* Read Write
* Mode Active -- Recovery -- Cycle IOMD type
* MW0 215 50 215 480 A
* MW1 80 50 50 150 C
