[PATCH] SuperH maintainership change

I think this is a time to step down from my SUPERH architecture
maintainerships.  The major development issues for this port seem to shift
on the hardwares I can't access and I have no recent activity on kernel.  I
shouldn't qualify as a maintainer of SUPERH port now and there is no
problem because Paul is actively maintaining it.  The attached patch drops
my name, address and web URL from MAINTAINERS file.
