fdc: take side count into account

fdc: most control commands do not generate interrupts
In fact, only three control commands generate an interrupt:read_id, recalibrate and seek
fdc: handle read-only floppies (abort early on write commands)
A real floppy doesn't attempt to write to read-only media either.
fdc: add CCR (Configuration Control Register) write register
DIR and CCR registers share the same address ; DIR is read-onlywhile CCR is write-only
CCR register is used to change media transfer rate, which will bechecked in following changes.

Floppies must be read at a specific transfer rate, depending of its own format.Update floppy description table to include required transfer rate.
