Bastian Koppelmann 11760a9993 sram_factory: Add check for duplicate module name 
sram_factory cannot handle duplicate module name, thus we bail out and
raise an error if a user attempts that.

Bastian Koppelmann 1df16eceb6 sram_factory: Give proper priority to overrides 
modules overridden by the user are the highest priority, then modules
overridden by the technology. If nothing is overriden, use the defaults
from OPTS (if they exist) or use the requested module_type.

This fixes that custom tech_modules could not be used, if they had a default in
OPTS even if the latter was not overridden by the user.

We don't need extra defaults in the tech_modules, as we now only use them,
if they have been overridden by the tech_module.
