Add console-polled.h and update all BSPs that should use it.

The file console-polled.h provides the prototypes for the three
required methods when implementing a single port polled console
driver. This paradigm is common on simulators and simple hardware.

+ Updated the BSPs Makefile.am to make console-polled.h available.
+ Regenerated the BSPs preinstall.sm.
+ Updated console support files to include <bsp/console-polled.h>.
+ Updated console support files to make printk() support method static.
