x86: unify kernel_physical_mapping_init() call in init_memory_mapping()

Impact: cleanup

The 64-bit version of init_memory_mapping() uses the last mapped
address returned from kernel_physical_mapping_init() whereas the
32-bit version doesn't. This patch adds relevant ifdefs to both
versions of the function to reduce the diff between them.
