The default chip driver (chip_generic) use command 01H + 2 bytes to
clear the QE bit. However this will accidently change the configuration
register value of the MXIC chip.
MXIC chip driver is added to fix that.

- checks if header really compiles (previously validated only by
preprocessor)
- checks that the header produced empty object, no inline code to be
present in public headers
