powerpc: export ppc_proc_freq and ppc_tb_freq as GPL symbols

Browse Source 
Export the global variable 'ppc_tb_freq', so that modules (like the Book-E
watchdog driver) can use it.  To maintain consistency, ppc_proc_freq is
changed to a GPL-only export.  This is okay, because any module that needs
this symbol should be an actual Linux driver, which must be GPL-licensed.
