STM32: Fetch Latest Drivers

[HTRamsey]

Description

• Fetch latest Eth drivers rather than providing a static set.
• Allows easy updating in the future, and avoids spelling/formatting CI checks.
• Also provides some minor fixes/updates due to updating the Eth drivers.
• Replaces STM32 network interface bug fixes #1253

Test Steps

Checklist:

• I have tested my changes. No regression in existing tests.

@bjsowa since you were the one who wrote the cmake part originally, thoughts on this?

[bjsowa]

Looks good but would be a bit problematic in my application as I am using nix to build it and I need to have all of the sources available before building it. Is using git submodules instead an option?

[HTRamsey]

Either way. I used FetchContent because this repo was already using it elsewhere to get the kernel

@HTRamsey Thanks for this contribution. Are those tags mentioned in the fetch content the same version of the drivers that are being removed? If it's a newer version, did you get a chance to verify the new drivers?

I see that STM32F4 and F7 got a new driver release (minor version) a few days back.

It's a newer version with a few changes. I've only really verified the ethernet files and have no idea about the rest of the HAL drivers because I don't use them. But as far as the ethernet changes go a couple of the changes are actually pretty important fixes to the reception process and the rest are related to PTP so not as important. I've tried the latest H7 and F7, which should translate to the F4 and H5 pretty well.
