imxtools: introduce hwemul

The hwemul tool is a small binary blob running on the device
that can received commands over USB. It is mainly intended to be
loaded using the recory mode and allows to read/write registers,
memory, use the OTP device, ... The tool is split into three
parts: dev/ contains the actual blob (which handles both imx233
and stmp3700), lib/ contains the communication library and can
also use the register description produced by the regtools/
to ease register by name, tools/ contains an interactive tool
to send commands to the device when running the blob.
