Documentation: move SCSI parameters to their own text file

Move SCSI parameters from kernel-parameters.txt to their own text file.

This continues a trend of moving non-core parameters out of
kernel-parameters.txt.

SCSI Kernel Parameters
~~~~~~~~~~~~~~~~~~~~~~
See Documentation/kernel-parameters.txt for general information on
specifying module parameters.
This document may not be entirely up to date and comprehensive. The command
"modinfo -p ${modulename}" shows a current list of all parameters of a loadable
module. Loadable modules, after being loaded into the running kernel, also
reveal their parameters in /sys/module/${modulename}/parameters/. Some of these
parameters may be changed at runtime by the command
"echo -n ${value} > /sys/module/${modulename}/parameters/${parm}".
