Added more status bytes for the mitsumi drive. This is only an ugly

Browse Source 
hack in the moment for testing purposes and to get the drive going
again.
0x20 means empty drive.
0x30 means closed drive with CDROM inserted.
0x80 means drive pulled out, but door closed.
0xa0 means drive pulled out and door open.
Luckily none of these values are the same as that reported for Ethernet
cards ( 0 for WD8003E, 0x40 for WD8013EPC, 0x60 for NE2000).
The bad part is, the probe code gets the WD8003E so hosed, that it is
no longer usable after it. No problem with the WD8013EPC.
