drm/amd/display: Turn functions into static

Silence [-Wmissing-prototypes] sparse warnings from the display folder
such as:

../drivers/gpu/drm/amd/amdgpu/../display/dc/clk_mgr/dcn315/dcn315_smu.c:126:5: warning: no previous prototype for ‘dcn315_smu_send_msg_with_param’ [-Wmissing-prototypes]
  126 | int dcn315_smu_send_msg_with_param(
      |     ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

v2: drop unused function dcn315_smu_set_voltage_via_phyclk() to avoid
    adding a warning (Alex)
