nfc: s3fwrn5: Remove wrong vendor prefix from GPIOs
The device tree property prefix describes the vendor, which in case of S3FWRN5 chip is Samsung. Therefore the "s3fwrn5" prefix for "en-gpios" and "fw-gpios" is not correct and should be deprecated. Introduce properly named properties for these GPIOs but still support deprecated ones.
