target/sparc: remove MemoryRegionSection check code from sparc_cpu_get_phys_page_debug()
This code is preventing the MMU debug code from displaying virtual
mappings of IO devices (anything that is not located in the RAM).
Before this patch, Qemu would output 0xffffffffffffffff (-1) as the
physical address corresponding to an IO device virtual address.
With this patch the intended physical address is displayed.
