can: tcan4x5x: Remove checking the wake pin
Remove checking the wake pin for every read/write call. The device is not explicitly put to sleep in the code and the POR interrupt is cleared during the init of the device. Signed-off-by: Dan Murphy <dmurphy@ti.com> Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de>
