Deprecate Unicore32 port

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
