pmem: fix BUG() error in pmem.h:48 on X86_32
After 'commit fc0c2028135c ("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().
