programmer: Add get_region to spi/opaque masters

Add a get_region function to spi and opaque masters so that they can
expose access permissions for multiple regions within the flash.

A get_region() implementation is added for the ichspi driver in a
following patch.

Finally, another patch uses get_region() to make read_flash() and
write_flash() skip inaccessable regions, making read, write, and erase
operations work on Intel platforms with active an CSME coprocessor.

This logic will be integrated with layout in the future, but for now
this moves ichspi support forward without making refactoring too hard
later on.
