Instead of blacklisting which architectures support MMUs (mandatorily or optionally), introduce two Kconfig options that are selected by each architecture in each case. This simplifies the logic in BR2_USE_MMU.

Provide the directory path that contains the overlay file

These overlay files are tar packages with updated configuration

configurations. They are provided by the processor vendor or

directly from Tensilica.
