WARNS here only has null or negative effects.

NO_MAN is not needed here.

Start the dreaded NOFOO -> NO_FOO conversion.

OK'ed by: core

Bump WARNS to 2 for all other ACPI drivers and minor cleanup.

Add acpi_if.h dependencies to module build.

Add the ACPI standard video extensions driver. I've done some style cleanup
but a bit more reamins to be done. For now, it is usable.
