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.
