scsi: Add missing MODULE_DESCRIPTION() macros

On x86, make allmodconfig && make W=1 C=1 reports:
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/scsi/scsi_common.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/scsi/advansys.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/scsi/BusLogic.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/scsi/aha1740.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/scsi/isci/isci.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/scsi/elx/efct.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/scsi/atp870u.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/scsi/ppa.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/scsi/imm.o

Add all missing invocations of the MODULE_DESCRIPTION() macro.

This updates all files which have a MODULE_LICENSE() but which do not have
a MODULE_DESCRIPTION(), even ones which did not produce the x86
allmodconfig warnings.
