[PATCH] drm/amdgpu/display: make various arrays static, makes object smaller

[Colin King]

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

Don't populate the arrays on the stack but instead make them
static. Makes the object code smaller by 158 bytes.

Before:
   text    data     bss     dec     hex filename
  32468    2072       0   34540    86ec display/dc/bios/bios_parser.o
  22198    1088       0   23286    5af6 display/dc/bios/bios_parser2.o
  22278    1076       0   23354    5b3a display/dc/dce/dce_mem_input.o

81180
After:
   text    data     bss     dec     hex filename
  32341    2136       0   34477    86ad display/dc/bios/bios_parser.o
  22070    1184       0   23254    5ad6 display/dc/bios/bios_parser2.o
  22119    1172       0   23291    5afb display/dc/dce/dce_mem_input.o

(gcc version 9.2.1, amd64)
