Add support for Legion Pro 7 16IAX10H (Q7CN, EC 0x5508)

[ChaoticSi1ence]

Add model_q7cn config for the 2025 Legion Pro 7 16IAX10H (83F5):

• EC chip: ITE IT5508 (0x5508), verified on hardware
• BIOS code: Q7CN
• Fan curve/speed/temperature via WMI3
• Power mode and fan full speed via WMI
• RGB keyboard is USB-controlled (ACCESS_METHOD_NO_ACCESS)
• Based on model_nscn (Legion 7 16IAX9) as closest match

Also fix minor line-length formatting in platform_profile_probe and platform_profile_init to comply with 80-column kernel style.

CI Failure Analysis

Pushed commit 13dc531 to fix checkpatch //-style comment warnings in my Q7CN model code (now uses /* */ block comments).

Remaining CI failures are pre-existing on main

My PR only modifies kernel_module/legion-laptop.c (+36 lines). The Run Tests job failures are all in upstream code untouched by this PR:

Failure	Root Cause
checkpatch.pl (step 4)	Runs against the entire 6500-line file. The ~60 //-spacing warnings, spelling typos (temmperature, hysteris, etc.), and remaining long lines all pre-date this PR.
pylint (step 5)	Warnings in legion_gui.py (unused vars w/h, broad-except) and legion_cli.py (unnecessary lambdas, unused **kwargs, broad-except) — all in boot logo code not touched by this PR.
test_python_cli.sh (step 6)	ModuleNotFoundError: No module named 'PIL' — legion.py imports from PIL import Image but Pillow is not listed in setup.cfg install_requires nor installed by any CI dependency script.
python_install_pip_pkg.sh	git describe --tags fails in CI's shallow checkout (no tags fetched).

These would need a separate upstream fix. Happy to open an issue or a follow-up PR for them if that would help.

@ChaoticSi1ence may I ask you why did you close this PR without merging?

I wanted to take it further and been messing with the whole project on my fork. I have it working 90% on my machine but I don't want to PR AI work over human code.

I own a Legion Pro 7 16AFR10H having the same EC 0x5508 controller and done some tests.
You can find what I have found at #385 (comment)

Maybe it can help in your review.

Ping me if you need infos or tests

I'm not sure how to implement your device into my work, I had completely pulled acpi and wmi info from windows to get it set up. This is no longer a project that is expandable for me as the code for LLL is very broken. You can try my fork and add your model to the kernel.c and copy my profile. I was tired of waiting for this project to do anything significant so I just slammed it with Claude Opus 4.6 and it almost fully works on my laptop. So I closed my pull request sadly. I'm not a dev.
