Kernel/Storage: Remove the stale ATAPIDiscDevice class

Browse source 
We don't really support ATAPI (SCSI packets over ATA channels) and it's
uncertain if we ever will support such type of media. For this reason,
there's basically no reason to keep this code.
If we ever introduce ATAPI support into the Kernel, we can simply put
this back into the codebase.
