[PATCH 3/5] drm/amd/display: make dcn32_link_encoder_is_in_alt_mode and dcn32_link_encoder_get_max_link_cap static

[Jiapeng Chong]

These two functions are not used outside the function
dcn32_dio_link_encoder.c, so the modification is defined as static.

drivers/gpu/drm/amd/amdgpu/../display/dc/dcn32/dcn32_dio_link_encoder.c:121:6: warning: no previous prototype for ‘dcn32_link_encoder_is_in_alt_mode’.
