Merge series from srinivas.kandagatla@linaro.org:

This patchset adds support for.
	1. parse Display Port module tokens from ASoC topology
	2. add support to DP/HDMI Jack events.
	3. fixes a typo in function name in sm8250

Verified these patches on X13s along with changes to tplg in
https://git.codelinaro.org/linaro/qcomlt/audioreach-topology/-/tree/topic/x13s-dp?ref_type=heads
and ucm changes from https://github.com/Srinivas-Kandagatla/alsa-ucm-conf/tree/topic/x13s-dp

x1e80100 is verified by Krzysztof with his changes in tplg
