MLK-20224 ARM64: dts: freescale: imx8qxp: disable cpu-idle by default 

With cpu-idle enabled, we observe that DSI panel display is NOT
working on i.MX8QXP MEK board, still under debugging, since cpu-idle
ONLY saves ~15mA in runtime, it is NOT valuable enough compare to
whole system, so disable it for now until everything is stable enough.
