SeaBIOS Kconfig: Update logging
The SeaBIOS and coreboot log levels don't really align, so setting the SeaBIOS log level to the same as coreboot's isn't really what we want. - Update default log level to use the default SeaBIOS log level. - Update the current help text to match the new defaults. - Add help text for what is displayed at various levels. - Get rid of separate type & prompt lines. - Add comments for default seabios level & logging disabled Change-Id: I5a8b75bd44748cb94a83a77ac3a379c8a9587e7b Signed-off-by: Martin Roth <martinroth@google.com> Reviewed-on: https://review.coreboot.org/18210 Tested-by: build bot (Jenkins) Reviewed-by: Nico Huber <nico.h@gmx.de> Reviewed-by: Kevin O'Connor <kevin@koconnor.net>
