[PATCH 1/2] [v2] powerpc: export ppc_proc_freq and ppc_tb_freq as GPL symbols

[Timur Tabi <timur@freescale.com>]

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.

Signed-off-by: Timur Tabi <timur@freescale.com>

This export is necessary for the Book-E watchdog driver to be compiled as a
module.
