Don't populate the array list on the stack but instead it
static const. Makes the object code smaller by 110 bytes:

Before:
   text    data     bss     dec     hex filename
  37713   21992      64   59769    e979 .../tegra/tegra210-emc-cc-r21021.o

After:
   text    data     bss     dec     hex filename
  37539   22056      64   59659    e90b .../tegra/tegra210-emc-cc-r21021.o

(gcc version 10.3.0)
