drm/radeon: make array encoded_lanes static
Don't populate the read-only array encoded_lanes on the stack but instead it
static. Also makes the object code smaller by 97 bytes:
Before:
text data bss dec hex filename
38899 8064 0 46963 b773 ./drivers/gpu/drm/radeon/r600_dpm.o
After:
text data bss dec hex filename
38738 8128 0 46866 b712 ./drivers/gpu/drm/radeon/r600_dpm.o
(gcc version 11.2.0)
