[PATCH 1/2] powerpc: export ppc_tb_freq so that modules can reference it

[Timur Tabi]

Export the global variable 'ppc_tb_freq', so that modules (like the Book-E
watchdog driver) can use it.

This export is necessary for the Book-E watchdog driver to be compiled as a
module.  Since ppc_proc_freq is already exported, I figured it's okay for
ppc_tb_freq to be exported as well.
