[PATCH 1/2] drm/amd/display: make is_synaptics_cascaded_panamera static

[Jiapeng Chong]

This symbol is not used outside of amdgpu_dm_mst_types.c, so marks it
static.

drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm_mst_types.c:211:6: warning: no previous prototype for ‘is_synaptics_cascaded_panamera’.
