Aboorva Devarajan 2dc019ca39 powerpc/time: Expose boot_tb via accessor ...

- Define accessor function get_boot_tb() to safely return boot_tb value,
  this is only needed when running in SPLPAR environments, so the
  accessor is built conditionally under CONFIG_PPC_SPLPAR.

- Tag boot_tb as __ro_after_init since it is written once at initialized
  and never updated afterwards.
