The mxc_arch_reset_init() uses static mapping and calls clk_get_sys() to get clock. It's suitable for non-DT boot but not for DT boot where dynamic mapping and of_clk_get() should be used instead. Create mxc_arch_reset_init_dt() as the DT variant of mxc_arch_reset_init(), and change DT platforms to use it. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
