ide: doc: remove compilation options section from ide-cd documentation

Browse source 
This section pointed out to compilation options which no longer exist.

VERBOSE_IDE_CD_ERRORS has been replace by config option
CONFIG_BLK_DEV_IDECD_VERBOSE_ERRORS.

STANDARD_ATAPI is no longer needed, since the non-standard drivers, which
required bcd2bin are now detected, and there's a flag for them.

NO_DOOR_LOCKING is now a sysctl parameter for cdrom drivers.

CDROM_NBLOCKS_BUFFER is not used anymore. The READAUDIO is now in cdrom.c and it
allocates as much as user space has requested to read, backing off if it fails.

TEST is not there anymore or in cdrom either. ide allows to send ATA commands
through ioctl, although it may be helpful to send MMC packets through the cdrom
layer directly.

4. Compilation options 4. Common problems
----------------------
There are a few additional options which can be set when compiling the
driver. Most people should not need to mess with any of these; they
are listed here simply for completeness. A compilation option can be
enabled by adding a line of the form `#define <option> 1' to the top
of ide-cd.c. All these options are disabled by default.
VERBOSE_IDE_CD_ERRORS
If this is set, ATAPI error codes will be translated into textual
descriptions. In addition, a dump is made of the command which
provoked the error. This is off by default to save the memory used
by the (somewhat long) table of error descriptions.
STANDARD_ATAPI
If this is set, the code needed to deal with certain drives which do
not properly implement the ATAPI spec will be disabled. If you know
your drive implements ATAPI properly, you can turn this on to get a
slightly smaller kernel.
NO_DOOR_LOCKING
If this is set, the driver will never attempt to lock the door of
the drive.
CDROM_NBLOCKS_BUFFER
This sets the size of the buffer to be used for a CDROMREADAUDIO
ioctl. The default is 8.
TEST
This currently enables an additional ioctl which enables a user-mode
program to execute an arbitrary packet command. See the source for
details. This should be left off unless you know what you're doing.
