Merge tag 'imx-clk-common-fixes' of git://git.pengutronix.de/git/imx/linux-2.6 into fixes

From Sascha Hauer: "Some fixes for the fresh i.MX common clock support"

Resolved trivial conflict in arch/arm/plat-mxc/include/mach/common.h.

* tag 'imx-clk-common-fixes' of git://git.pengutronix.de/git/imx/linux-2.6:
  ARM: imx6q: prepare and enable init on clks directly instead of clk_get first
  ARM i.MX: remove now unnecessary argument from mxc_timer_init
  ARM: i.MX: change timer clock from ipg to perclk
  ARM i.MX5: fix gpt peripheral clock path
