asus-laptop: add base driver

Adds the new driver and make ASUS_LAPTOP and ACPI_ASUS
incompatible.  It may be strange to use ASUS_CREATE_DEVICE_ATTR
and ASUS_SET_DEVICE_ATTR now, but these macro will be very
usefull in next patchs.  ASUS_HANDLE and ASUS_HANDLE_INIT comes
from IBM_HANDLE and IBM_HANDLE_INIT, with some modification,
and will also be used in next patchs.
