Douglas Teles 36f99fec2b soysauce: speaker output via rk817 external amplifier
The R35S/Y3506 loudspeaker is not wired to the rk817 class-D SPKO; it
hangs off the analog headphone output through an external amp gated by
spk-ctl-gpios. The mainline codec routes "SPK" to the unused class-D, so
the speaker is silent. Add patch 0060 (use_ext_amplifier: route the
speaker mux through the headphone DACs and toggle spk-ctl via a DAPM
event) and the per-device audio playback paths (SPK/HP) so the speaker
plays and headphone switching works.
