block: Rework drivers/cdrom/Makefile

Browse Source 
Instead of referring from inside drivers/cdrom/Makefile to all the
drivers that use this driver, let these drivers select the cdrom
driver. This change makes the cdrom build code follow the approach
that is used for most other drivers, namely refer from the higher
layers to the lower layer instead of from the lower layer to the
higher layers.

A CD-ROM is a pre-pressed optical compact disc which contains
data. The name is an acronym which stands for "Compact Disc
Read-Only Memory". This driver implements functionality that is
shared by all CD-ROM drivers, e.g. the IDE CD-ROM driver and the
SCSI CD-ROM driver. For a list of the ioctls implemented by this
driver, see also Documentation/ioctl/cdrom.txt.
