ARM: imx: move clk_prepare() out from mxc_restart()
It's inappropriate to call clk_prepare() in mxc_restart(), because the restart routine could be called in atomic context. Move clk_get() and clk_prepare() into mxc_arch_reset_init() and only have the atomic part clk_enable() be called in mxc_restart(). As a result, mxc_arch_reset_init() needs to be called after clk gets initialized. While there, it also changes printk(KERN_ERR ...) to pr_err() and adds __init annotation for mxc_arch_reset_init(). Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
