Now we have removed all the board types that it covers, we can move
the text about old Arm boards from deprecated.rst to
removed-features.rst, tweaking it appropriately.

QEMU includes models of some machine types where the QEMU code that
emulates their SoCs is very old and unmaintained. This code is now
blocking our ability to move forward with various changes across
the codebase, and over many years nobody has been interested in
trying to modernise it. We don't expect any of these machines to have
a large number of users, because they're all modelling hardware that
has now passed away into history. We are therefore dropping support
for all machine types using the PXA2xx and OMAP2 SoCs. We are also
dropping the ``cheetah`` OMAP1 board, because we don't have any
test images for it and don't know of anybody who does; the ``sx1``
and ``sx1-v1`` OMAP1 machines remain supported for now.
