Fix DT kselftest failures on mt8186-steelix

[nfraprado]

Current DT kselftest failures on linux-next:

• /soc/dpi@1400a000, /soc/i2c@1100f000/dp-bridge@5c: The logs shows errors it6505 3-005c: can not get extcon device! and platform 1400a000.dpi: deferred probe pending: mediatek-dpi: Failed to get bridge. Applying this old series (actually those commits + fixup from this branch, since they no longer apply) fixed the failure;
• /soc/i2c@11009000/trackpad@2c: Second source component like the trackpad on juniper. Depends on series https://lore.kernel.org/all/[email protected]/ being merged to be fixed.
• /sound: On the logs there's platform sound: deferred probe pending: mt8186_mt6366: I2S3: codec dai not found. From DT, I2S3's codecs are the it6505 dp-bridge and rt1019 speaker-codec, but even with both probing the issue persists. Note that UCM hasn't been merged upstream yet, so working audio is blocked on that, but this isn't required to get the driver probing.
