ARM: dts: imx6qdl-sabre*: fix Egalax touchscreen properties

This patch fixes interrupt trigger (should be level low as that is what the
driver is always using), the GPIO that is the interrupt source that is also
used to wake up chip by driving the line low.

The proper polarity is be needed for converting the driver to gpiod API.
