Deprecate Unicore32 port

Browse Source 
Deprecate our Unicore32 target support:
 * the Linux kernel dropped support for unicore32 in commit
   05119217a9bd199c for its 5.9 release (with rationale in the
   cover letter: https://lkml.org/lkml/2020/8/3/232 )
 * there is apparently no upstream toolchain that can create unicore32
   binaries
 * the maintainer doesn't seem to have made any contributions to
   QEMU since the port first landed in 2012
 * nobody else seems to have made changes to the unicore code except
   for generic cleanups either

The ``unicore32`` guest CPU support is deprecated and will be removed in
a future version of QEMU. Support for this CPU was removed from the
upstream Linux kernel, and there is no available upstream toolchain
to build binaries for it.
