[PATCH] scsi: ufs: make array setup_attrs static const, makes object smaller

[Colin King]

From: Colin Ian King <colin.king@canonical.com>

Don't populate the array setup_attrs on the stack but instead make it
static const. Makes the object code smaller by 180 bytes.

Before:
   text	   data	    bss	    dec	    hex	filename
   2140	    224	      0	   2364	    93c	drivers/scsi/ufs/ufshcd-dwc.o

After:
   text	   data	    bss	    dec	    hex	filename
   1863	    320	      0	   2183	    887	drivers/scsi/ufs/ufshcd-dwc.o

(gcc version 9.2.1, amd64)

Applied to 5.5/scsi-queue. Thanks!
