As a preparation for moving all IDE commands into their own function
like in the ATAPI code, introduce a 'handler' callback to ide_cmd_table.
Commands using this new infrastructure get some things handled
automatically:
* The BSY flag is set before calling the handler (in order to avoid bugs
like the one fixed in f68ec837) and reset on completion.
* The (obsolete) DSC flag in the status register is set on completion if
the command is flagged with SET_DSC in the command table
* An IRQ is triggered on completion.
* The error register and the ERR flag in the status register are cleared
before calling the handler and on completion it is asserted that
either none or both of them are set.
No commands are converted at this point.

If DriveKind changes there could be unnoticed collisions and in the
meantime we have empty flags bits...
Creating a single IDEHandlerFlags enum would still depend on
IDEDriveKind constants so I don't see a nicer solution than what you've
done. We can live with this.

cmd_nop handles all commands that don't really do anything in our
implementation except setting status register flags.
