[RFC PATCH 0/8] clk: qoriq: Move chip-specific knowledge into driver

Sorry for not responding to this one sooner. Fell through the cracks.

All of the changes to drives/clk/clk-qoriq.c look great to me. I assume
you need to keep all of these patches together and want to the take
through the freescale tree? If so feel free to add,
