[PATCH 12/15] clk: Add Layerscape clk support

[Sascha Hauer <s.hauer@pengutronix.de>]

This adds support for the clock controller found on Layerscape
SoCs. This is mostly an adoption of the corresponding Linux
driver. This is tested on the LS1046a SoC. Other ARM based Layerscape
SoCs should work aswell, support for the PowerPC based SoCs has
been removed.
