Lucas Stach 2938090556 ARM: imx6: disable deeper idle states when FEC is active w/o HW workaround
The i.MX6 Q/DL has an erratum (ERR006687) that prevents the FEC from
waking the CPUs when they are in wait(unclocked) state. As the hardware
workaround isn't applicable to all boards, disable the deeper idle state
when the workaround isn't present and the FEC is in use.

This allows to safely run a kernel with CPUidle enabled on all i.MX6
boards.
