Subject: [PATCH 00/11] Drop default ARCH_APPLE from Kconfig and use
 defconfig instead

Hi,

When support for Apple Silicon was originally upstreamed we somehow
started using `default ARCH_APPLE` for most drivers. arm64 defconfig
also contains ARCH_APPLE=y such that this will turn into `default y`
there by default which is neither what we want nor how this is usually
done.
Let's fix all that by dropping the default everywhere and adding the
drivers to defconfig as modules instead of built-ins.
None of these patches depend on each other so we can just take them all
independently through the respective subsystem trees.

Best,

Sven
