[PATCH 01/21] ide-floppy: convert to generic packet commands

[Borislav Petkov <bbpetkov@yahoo.de>]

Replace the ide-floppy packet commands opcode defines with the generic ones.
Add a missing GPCMD_WRITE_12 (opcode 0xaa) to the generic ones in cdrom.h. The
last one can be found in the current version of INF-8090, p.905.
