Also fixes a bug that causes the device tree property check to always
pass.

The TRF7970A has configuration options to support hardware designs
which use a 27.12MHz clock. This commit adds a device tree option
'clock-frequency' to support configuring the this chip for default
13.56MHz clock or the optional 27.12MHz clock.

Thanks Mark. Should I resubmit patches with the requested edits today, or
wait a bit for more comments? What is the desired etiquette?

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

Mark, from our consultant:
It isn't important whether the flood script is successful in writing
or not. The point of it is to force a segfault by making many
requests. It needs to run for several hundred iterations (successful
or not) in order to generate the segfault.
