[PATCH v2 2/4] console: add function console_devices_set

[Patrick Delaunay]

From: Patrick Delaunay <patrick.delaunay at st.com>

Add a new function to access to console_devices only defined if
CONFIG_IS_ENABLED(CONSOLE_MUX).

This path allows to remove #if CONFIG_IS_ENABLED(CONSOLE_MUX)
in console_getc function.
