ARM: imx: add cpu idle support for i.MX6SLL
i.MX6SLL supports cpu idle with ARM power gated, it can reuse i.MX6SX's cpu idle driver to support below 3 states of cpu idle: state0: WFI; state1: WAIT mode with ARM power on; state2: WAIT mode with ARM power off. L2_PGE in GPC_CNTR needs to be cleared to support state2 cpu idle. Signed-off-by: Anson Huang <Anson.Huang@nxp.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
