powerpc: fix memory leaks in QE library
Fix two memory leaks in the Freescale QE library: add a missing kfree() in
ucc_fast_init() and ucc_slow_init() if the ioremap() fails, and update
ucc_fast_free() and ucc_slow_free() to call iounmap() if necessary.
Based on a patch from Tony Breeds <tony@bakeyournoodle.com>.
