powerpc: Export memstart_addr and kernstart_addr on ppc64

Some modules (like eHCA) want to map all of kernel memory, for this to
work with a relocated kernel, we need to export kernstart_addr so
modules can use PHYSICAL_START and memstart_addr so they could use
MEMORY_START. Note that the 32bit code already exports these symbols.
