Support for these boards has been removed from the Linux kernel
in version 6.3 in 2023, so there are likely no users left for these
boards. Time to mark them as deprecated in QEMU, too!

While Linux host support makes sense for code removal, guest
support isn't relevant IMHO. I.e. you can still run U-boot
or any guest code you fancy, like my-first-rtos.

(I noticed Peter want a more generic removal)

I agree that we should drop these, but I would like to be more
drastic -- see my other email in the "possible deprecation and
removal of some old QEMU Arm machine types (pxa2xx, omap, sa1110)"
thread.

thanks

Even better! Looking forward to your patch :-)
