Geoff Lansberry 49d22c70aa NFC: trf7970a: Add device tree option of 1.8 Volt IO voltage 
The TRF7970A has configuration options for supporting hardware designs
with 1.8 Volt or 3.3 Volt IO.   This commit adds a device tree option,
using a fixed regulator binding, for setting the io voltage to match
the hardware configuration. If no option is supplied it defaults to
3.3 volt configuration.
