Johan Hovold c3953a3c2d 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.

Fixes: e33a3f84f8 ("NFC: nfcmrvl: allow gpio 0 for reset signalling")
