dt-bindings: usb: cypress,cypd4226: Drop Tegra specific GPIO defines

The Tegra GPIO define is a problem for the magic code which extracts
the examples and fixes up the interrupt provider. This was partially
worked around by putting #interrupt-cells in the parent. However,
that's incomplete and causes a warning when dtc "interrupt_provider"
check is enabled. Just drop the Tegra specific define and simplify
the example.
