arm64: dts: qcom: sdm660-bbry-common: fix reserved-mem ranges, panel regulators, and syna ts

[sajattack]

Passes memtest now. Copied from downstream with some tweaks. Tested remoteproc and wifi still work.

Also adding lcd panel regulators to fix syna flakiness and tweaking touchscreen delays.

Adds ton of new errors to dtbs-check (see checks tab), plz fix 👉 👈

There's an error: https://github.com/sdm660-mainline/linux/actions/runs/22894143872/job/66423921180?pr=174#step:11:22

[minlexx]

Lexical error: Documentation/devicetree/bindings/display/panel/boe,bv045fhm-l00.example.dts:29.35-50 Unexpected 'GPIO_ACTIVE_LOW'

Forgottent #include for GPIO_ACTIVE_LOW definition? in bindings example..?

[minlexx]

This is huge delay :))

[sajattack]

It was failing to init if the display wasn't ready.

[minlexx]

Still feels too much, 1000 isn't enough?

[sajattack]

I think I tried 1200 at one point. Before it was at 600. 2000 seemed good for stability.

Would be even better if you could test the same change on top of setotau's 6.19.y branch and by doing so try 6.19 in general

I tested some of the changes on 7.0.0 already, but I can do that too.

I think I'll rebase on 7.0.0 soon

Ugh, I tried booting 6.19 on the athena-syna variant, and memtest got stuck again. I have more work to do.

false alarm, missed one of the commits in the cherry-pick, 6.19 looks good
