[opentitantool] OTP ROM patch partition generation tool

The OTP ROM patch opentitantool command generates an OTP image partition HJSON or a raw binary blob, from a second stage ROM patch description. The HJSON image partition can be used directly as an OTP overlay in order to include it into a final OTP image. Signed-off-by: Samuel Ortiz <[email protected]>
