Pull Request Details 📖

Description

Since users seem to struggle with including the rom_functions.x from esp-wifi we now include everything needed in esp-hal which shouldn't hurt. Hopefully also the process of updating is a bit easier now.

Once this PR landed there will be a follow up PR to remove the linker scripts from esp-wifi-sys.

skip-changelog because of changes in esp-hal

To be fair I'm pretty sure that "No need to include rom_functions.x manually" belongs to the changelog :D That, or the migration guide is in the wrong crate :)

mhhhh - but that applies to esp-wifi not esp-hal (and it's mentioned in esp-wifi's changelog)

But the migration guide you edited applies to esp-hal 🙃
