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
itself. Unfortunately, it gets it right in some cases. So rather than
fix that logic, just drop it in favor of using 16bit signed casts. Now
gcc will take care of getting the logic right.
