Applied to u-boot/master, thanks!
When there is no CDROM inserted, the block size is zero hence there is no need to create a BLK device for it.

At present the IDE device number is initialized to -1, which means we cannot type "ide read" command before setting the device number via "ide device #".
For convenience, let's set the first device as the default one.
