gpio: rcar: Support both edge trigger with DT
Some versions of the R-Car GPIO controller support triggering on both edges of the input signal. Whether this capability is supported is currently specified in platform data. R-Car GPIO devices instantiated from the device tree have the capability turned off even when the hardware supports it. To fix this, add DT match data support to the driver, initialize both edge trigger support from match data and enable both edge trigger in r8a7790 and r8a7791 match data.
