ARM: imx53: clk: add ARM clock
The ARM clock is a virtual clock feeding the ARM partition of the SoC. It controls multiple other clocks to ensure the right sequencing when cpufreq changes the CPU clock rate. Signed-off-by: Lucas Stach <l.stach@pengutronix.de> Signed-off-by: Shawn Guo <shawn.guo@freescale.com>
