pmem: fix BUG() error in pmem.h:48 on X86_32
After 'commit fc0c2028 ("x86, pmem: use memcpy_mcsafe() for memcpy_from_pmem()")', probing a PMEM device hits the BUG() error below on X86_32 kernel. kernel BUG at include/linux/pmem.h:48! memcpy_from_pmem() calls arch_memcpy_from_pmem(), which is unimplemented since CONFIG_ARCH_HAS_PMEM_API is undefined on X86_32. Fix the BUG() error by adding default_memcpy_from_pmem(). Acked-by:Dan Williams <dan.j.williams@intel.com> Signed-off-by:
