[PATCH][V2] media: cxd2820r: make arrays tab static const, makes object smaller

[Colin King]

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

Don't populate the array tab on the stack but instead make it
static const. Makes the object size smaller by 170 bytes in total.

Before:
   text    data     bss     dec     hex filename
   7045    1736       0    8781    224d media/dvb-frontends/cxd2820r_c.o
   8800	   2216	      0	  11016	   2b08	media/dvb-frontends/cxd2820r_t.o
   8981	   2120	      0	  11101	   2b5d	media/dvb-frontends/cxd2820r_t2.o

After:
   text    data     bss     dec     hex filename
   6896    1832       0    8728    2218 media/dvb-frontends/cxd2820r_c.o
   8651	   2312	      0	  10963	   2ad3	media/dvb-frontends/cxd2820r_t.o
   8853	   2184	      0	  11037	   2b1d	media/dvb-frontends/cxd2820r_t2.o

(gcc version 9.2.1, amd64)
