rpi-kernel: split into rpi, rpi2, rpi3
Until now, rpi-kernel served rpi0/rpi1 + rpi2 + rpi3 all at once.  The
variants were solely distiguished by the target architecture; it was
nice while it lasted, but now that rpi4 is on its way, we need to split
things up a little.

With the split,
* rpi-kernel serves rpi0 + rpi1, armv6l* only
* rpi2-kernel serves rpi2, armv7l* only
* rpi3-kernel serves rpi3, aarch64* only

To help migrate existing devices to the new kernel packages, rpi-kernel
will be an empty mega package for !armv6l* and depend on rpi2-kernel or
rpi3-kernel (depending on target architecture) for the foreseeable
future, thus resolving like this:
* rpi-kernel -> rpi2-kernel (armv7l*)
* rpi-kernel -> rpi3-kernel (aarch64*)

Relates to: #29139
