Blind support for the EMTEC Gdium Liberty netbook. Per-platform configuration

is moved to specific files, and a pointer to the key configuration structure
is now kept in struct sys_config.
bonito(4) interrupt handling is split, to allow PCI+Legacy interrupt systems
(Lemote Yeelong) and PCI-only Legacy-free systems (Gdium) to coexist
peacefully.
