[PATCH 3/3] drm/amd/display: Remove set but not used variables 'regval', 'speakers'

[zhengbin]

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/gpu/drm/amd/display/dc/dce/dce_stream_encoder.c: In function dce110_update_generic_info_packet:
drivers/gpu/drm/amd/display/dc/dce/dce_stream_encoder.c:68:11: warning: variable regval set but not used [-Wunused-but-set-variable]
drivers/gpu/drm/amd/display/dc/dce/dce_stream_encoder.c: In function dce110_se_audio_setup:
drivers/gpu/drm/amd/display/dc/dce/dce_stream_encoder.c:1331:11: warning: variable speakers set but not used [-Wunused-but-set-variable]

They are not used since commit 4562236b3bc0 ("drm/amd/dc:
Add dc display driver (v2)")
