drm/amd/display: Remove unused variables from dcn10_stream_encoder

The variable regval from the function enc1_update_generic_info_packet
and the variables dynamic_range_rgb and dynamic_range_ycbcr from the
function enc1_stream_encoder_dp_set_stream_attribute are not currently
used.

This was pointed by clang with the following warnings:

drivers/gpu/drm/amd/amdgpu/../display/dc/dcn10/dcn10_stream_encoder.c:62:11:
warning: variable 'regval' set but not used [-Wunused-but-set-variable]
