There are no interrupt changes.
The console driver was rewritten between 4.9 and 4.10. It is possible
something slipped through the testing. You probably should compare the
two console drivers with a view toward the mode you are using.

* console/console.c: Removed.
* console/erc32_console.c: New file. Use shared console driver.
Make sure interrupt support works. PPPD confirmed on sis.
* Makefile.am: Reflect changes above.
