SPARC64: split cpu_get_phys_page_debug() from cpu_get_phys_page_nofault()
This patch makes cpu_get_phys_page_debug() independent from
cpu_get_phys_page_nofault() in advance of implementing nonfaulting load.
This also modifies cpu_get_phys_page_nofault() to be compiled only on
TARGET_SPARC64 because it is not required on SPARC32.
