This simulates a CFI flash. Its pretty configurable via the device
tree. For now, only basic read/write/erase operations are supported
for the Intel command set, but it's easy enough to extend support.
It's certainly enough to trick Das U-Boot into using it for probing,
reading, writing, and erasing.

The current implementation attempts to handle the 16bit sign extension

We need the DIR bit cleared, not set, in order for the pin to be treated

When looking up the data value, we need to shift the "level" value over by
"my_port" rather than "bit" as the latter has already been shifted over.
We also should normalize the "level" coming in from the outside worlds to
the set of {0,1} since those are the only values that matter to GPIOs.
