xen/ppc: Fix double xen_ulong_t typedef in public/arch-ppc.h

public/arch-ppc.h contains two adjacent #ifndef __ASSEMBLY__ blocks.

With these merged, it becomes very obvious that there's a duplicate
definition of xen_ulong_t, which is also noticed by the docs build:

  /usr/bin/perl -w /local/xen.git/docs/xen-headers -O html/hypercall/ppc \
          -T 'arch-ppc - Xen public headers' \
          -X arch-arm -X arch-riscv -X arch-x86_32 -X arch-x86_64 \
          -X xen-arm -X xen-riscv -X xen-x86_32 -X xen-x86_64 \
          -X arch-x86 \
          /local/xen.git/docs/../xen include/public include/xen/errno.h
  include/public/memory.h:63: multiple definitions of Typedef xen_ulong_t: include/public/arch-ppc.h:55
  include/public/memory.h:63: multiple definitions of Typedef xen_ulong_t: include/public/arch-ppc.h:61
  include/public/memory.h:63: multiple definitions of Typedef xen_ulong_t: include/public/arch-ppc.h:61
  include/public/memory.h:63: multiple definitions of Typedef xen_ulong_t: include/public/arch-ppc.h:55

Drop the second typedef.  Finally, annotate the #endif so it's clear
what it refers to.
