media: tuners: mxl5005s: make arrays static const, reduces object code size

Browse Source 
Don't populate the arrays RegAddr on the stack, instead make them static
const.  Makes the object code smaller by over 980 bytes:

Before:
   text	   data	    bss	    dec	    hex	filename
  64923	    304	      0	  65227	   fecb	drivers/media/tuners/mxl5005s.o

After:
   text	   data	    bss	    dec	    hex	filename
  63779	    464	      0	  64243	   faf3	drivers/media/tuners/mxl5005s.o
