The patch series introduces a few cleanups aimed at reducing code duplication
in the console driver.

Originally, patches 2 and 3 were part of NS16550 emulator v3 series [1].

Patch 1 removes some code duplication for logging via conring facility.

Patch 2 (see [2]) removes code duplication between __putstr() and the rest of
the driver. It also introduces private flags to select console devices for
printout which simplifies some code paths.

Patch 3 (see [3]) adds conring_flush() to send contents of conring to all
currently available console devices.
