drm/amd/display: Remove set but not used variables 'pp_smu', 'old_pipe'

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

drivers/gpu/drm/amd/display/dc/dce110/dce110_hw_sequencer.c: In function dce110_enable_audio_stream:
drivers/gpu/drm/amd/display/dc/dce110/dce110_hw_sequencer.c:949:23: warning: variable pp_smu set but not used [-Wunused-but-set-variable]

drivers/gpu/drm/amd/display/dc/dce110/dce110_hw_sequencer.c:983:23: warning: variable pp_smu set but not used [-Wunused-but-set-variable]

'pp_smu' is not used since commit 170a2398d2d8 ("drm/amd/display:
make clk_mgr call enable_pme_wa")

'old_pipe' is not used since commit 65d38262b3e8 ("drm/amd/display:
fbc state could not reach while enable fbc")
