scsi: ips: make array 'options' static const, makes object smaller

Don't populate the array 'options' on the stack but instead make it static
const. Makes the object code smaller by 143 bytes.

Before:
   text	   data	    bss	    dec	    hex	filename
  94483	  11272	   1184	 106939	  1a1bb	drivers/scsi/ips.o

After:
   text	   data	    bss	    dec	    hex	filename
  94244	  11368	   1184	 106796	  1a12c	drivers/scsi/ips.o

(gcc version 9.2.1, amd64)
