patches-6.12: bcm27xx: refresh patch set

The patches were generated from the RPi repo with the following command:
git format-patch v6.12.5..rpi-6.12.y

Then used update_kernel.sh to rebase against 6.12.5.

Removed wireless drivers, Github workflows, and defconfigs patches.
The following was used to flag potential patches to exclude:

ls|grep -i brcm
ls|grep -i github
ls|grep -i config
ls|grep -i readme

Also helpful to grep for keywords in patches to manually inspect
like: grep defconfig *.patch
