NFC: trf7970a: Don't turn on RF if there is already an RF field
Currently, the trf7970a driver blindly turns on its
RF field when configuring its framing. This isn't
a good idea if there is already a device generating
an RF field. Instead, check if there is already an
RF field present before turning on this device's RF
field and, if there is, return EBUSY.
