lantiq: correct value for fpi clock on ar9
This adds a patch to target/linux/lantiq/patches-3.14
fixing a bug clock code on ar9. The current version returns
the wrong value for the fpi clock frequency in some
cases.
See discussion for further details:
https://lists.openwrt.org/pipermail/openwrt-devel/2015-January/030688.html
I'm not sure about the patch naming and numbering convention.
Do please let me know it this is not OK.
Many thanks,
Ben Mulvihill
