powerpc: fix linux-next build failure

Today's linux-next build (powerpc allyesconfig) failed like this:

In file included from arch/powerpc/include/asm/mmu-hash64.h:17,
                 from arch/powerpc/include/asm/mmu.h:8,
                 from arch/powerpc/include/asm/pgtable.h:8,
                 from arch/powerpc/mm/slb.c:20:
arch/powerpc/include/asm/page.h:76: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'memstart_addr'
arch/powerpc/include/asm/page.h:77: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'kernstart_addr'

Caused by commit 600715dc ("generic: add
phys_addr_t for holding physical addresses") from the tip-core tree.
This only fails if CONFIG_RELOCATABLE is set.

So include that instead of asm/types.h in asm/page.h for
the CONFIG_RELOCATABLE case.
