mpc85xx: add 3.14 kernel support for mpc85xx platform

This patch adds 3.14 kernel support for the mpc85xx platform.
Works fine here with a TL-WDR4900 which seems to be the only
supported device using this platform.
There might be differences depending on HW version, therefore
I'd ask others to test too.
