[PATCH][V2] ASoC: Intel: make const arrays static, reduces object code size

[Colin King]

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

Don't populate the const arrays on the stack but instead make
it static. Makes the object code smaller, for example:

Before:
   text    data     bss     dec     hex filename
  14107    8832     224   23163    5a7b bytcht_es8316.o

After:
   text    data     bss     dec     hex filename
  14015    8896     224   23135    5a5f bytcht_es8316.o

(gcc version 8.2.0 x86_64)

V2: also fix up bytcr_rt5640.c and bytcr_rt5651.c, thanks to
Pierre-Louis Bossart for noticing these two.
