NFC: nfcmrvl: fix gpio-handling regression
Fix two reset-gpio sanity checks which were never converted to use gpio_is_valid(), and make sure to use -EINVAL to indicate a missing reset line also for the UART-driver module parameter and for the USB driver. This specifically prevents the UART and USB drivers from incidentally trying to request and use gpio 0, and also avoids triggering a WARN() in gpio_to_desc() during probe when no valid reset line has been specified.
