kernel: qca-ssdk: update to 12.5 for kernel 6.6

[qosmio]

Qualcomm recently committed a new branch (12.5.r2) targeting kernel 6.6. This lets us clean up a few patches particularly the one for "C22/C45" mdio.

A quick way to see what changed for IPQ807x/6018 was to list the files produced during build (**/*.o), replace the extension with ".c", and doing a git log.

Filtering from those commits, ones of particular interest are listed below:

2024-04-16 - 0d8f30aa - fix compile issue on hk with linux style build

2023-10-03 - fb2e0401 - fix port5 interface mode switch issue in erp case

A lot of the build warnings have been fixed upstream too.

Included a patch to also address remaining build warnings for fal_eg_trans_filter_bypass_en_get and fal_eg_trans_filter_bypass_en_set.

Verified with users on QNAP 301W, NBG7815, and myself on Dynalink DL-WRX36 that everything is functional, including LEDS.

Thanks @qosmio . Should we also create a new PR for nss-dp 12.5.r2 branch?

Thanks for doing this, I started doing the update but then ran out of time, I really like lack of warnings :)

Maybe it's a good time to update qca-nss-dp too, so new PR for qca-nss-dp #15383

Happy to!

I agree, I use colormake, so it was really nice to no longer be seeing yellow and red pop up.

Feels good :)

Runs OK on fritz-repeater (ipq4019+qca8035 single ethernet)
Queues are (since recently I think) not equally filled, generating unequal interrupt loads on cores (each redirected to a different core)
