[PATCH-for-5.2 1/4] docs/system: Deprecate raspi2/raspi3 machine aliases

[Philippe Mathieu-Daudé]

Since commit aa35ec2213b ("hw/arm/raspi: Use more specific
machine names") the raspi2/raspi3 machines have been renamed
as raspi2b/raspi3b.

Note, rather than the raspi3b, the raspi3ap introduced in
commit 5be94252d34 ("hw/arm/raspi: Add the Raspberry Pi 3
model A+") is a closer match to what QEMU models, but only
provides 512 MB of RAM.

As more Raspberry Pi 2/3 models are emulated, in order
to avoid confusion, deprecate the raspi2/raspi3 machine
aliases.
