floppy: Fix accesses to DOR register.
The DOR register is a write-only register (even though QEMU and at
least some real hardware permit read/write acess). So, do not read
from the DOR port. Introduce a VARLOW variable (FloppyDOR) to store
the current state.
When resetting the controller, make sure to enable both the controller
and interrupts. Also, make sure the controller is really reset (by
writing a 0 to DOR first) to ensure an IRQ is received on reset.
Also, add some additional dprintf statements to the floppy init path.
