ata: pata_parport: fit3: implement IDE command set registers
fit3 protocol driver does not support accessing IDE control registers
(device control/altstatus). The DOS driver does not use these registers
either (as observed from DOSEMU trace). But the HW seems to be capable
of accessing these registers - I simply tried bit 3 and it works!
The control register is required to properly reset ATAPI devices or
they will be detected only once (after a power cycle).
Tested with EXP Computer CD-865 with MC-1285B EPP cable and
TransDisk 3000.
