[PATCH] media: imx7-mipi-csis: make array 'registers' static const, makes object smaller

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Don't populate the array 'registers' on the stack but instead make it
static const. Makes the object code smaller by 10 bytes.

Before:
   text	   data	    bss	    dec	    hex	filename
  20138	   5196	    128	  25462	   6376	staging/media/imx/imx7-mipi-csis.o

After:
   text	   data	    bss	    dec	    hex	filename
  20032	   5292	    128	  25452	   636c	staging/media/imx/imx7-mipi-csis.o

(gcc version 9.2.1, amd64)
