console: Introduce a way for mainboard to override the loglevel
This change adds a config option to allow mainboard to override
the console loglevel. When the option is set, the platform has
to define the function get_console_loglevel returning a valid
loglevel value.
This allows a mainboard to sample a GPIO to switch the loglevel
value between different environments (qualification vs production)
without re-flashing.
