ARM: dts: imx6qdl-sabrelite: remove erratum ERR006687 workaround
There is a pin conflict with GPIO_6. This pin functions as a power input pin to the OV5642 camera sensor, but ENET uses it as the h/w workaround for erratum ERR006687, to wake-up the ARM cores on normal RX and TX packet done events. So we need to remove the h/w workaround to support the OV5642. The result is that the CPUidle driver will no longer allow entering the deep idle states on the sabrelite. This is a partial revert of commit6261c4c8f1
