target/sparc: Use cpu_translate_for_debug()

Browse Source 
We want to remove the cpu_get_phys_addr_debug() function; update the
sparc dump_mmu() function to use cpu_translate_for_debug() instead.

The "mmu_probe succeeds but debug translate fails" cases are probably
not possible in practice; since cpu_get_phys_addr_debug() would
return -1 in that situation we make this conversion retain that
behaviour.
