Modernize kernel build for zero/rpi2/rpi3/rpi4

Description

See https://www.raspberrypi.org/documentation/linux/kernel/building.md

There are tweaks per platform, such as 32 vs 64 bit builds and which toolchain to build (64bit would use aarch64 which is not currently being built). I need to update the HW=<> option to make use of these.

The overlays and DTB's can be grabbed directly from the kernel build tree.

The build page referenced above still refers to the git repo that's been used for a while now.

This is mostly done but there are problems. The 64bit toolchains don't build the 5.10.y kernel. But 5.10.y isn't even an active tag on the RPi github repo anymore. So I need to bump to the latest active, which is 5.15.y.

This is more complex than I expected so this will go into a branch - RM-838. I'll return to it after I finish the 2.0 release (which I may not be able to do until I bump the kernel anyway).

This is no longer necessary since we won't do 64bit builds because omxplayer doesn't support them.

The rest of the component builds are updated to utilize the information from the raspberry pi documentation. There may be additional user space work to do based on that documentation but that work does not relate to kernel builds.

Closing issue.
