powerpc: Rely on generic definition of hugepd_t and is_hugepd when unused
CONFIG_ARCH_HAS_HUGEPD is used to tell core mm when huge page
directories are used.
When they are not used, no need to provide hugepd_t or is_hugepd(),
just rely on the core mm fallback definition.
For that, change core mm behaviour so that CONFIG_ARCH_HAS_HUGEPD
is used instead of indirect is_hugepd macro existence.
powerpc being the only user of huge page directories, there is no
impact on other architectures.
