ACPI: Delete Intel Customer Reference Board (CRB) from OSI(Linux) DMI list

Linux does not want BIOS writers to invoke _OSI(Linux) -
for in the field it causes more Windows incompatibility problems
than it solves.

So when it is seen in the BIOS for an Intel Customer Reference Board,
Linux should ignore its effect by default, and should complain loudly.
Otherwise, the reference BIOS will go unfixed, and the bad BIOS
will spread to the field.

Users of this board can get the old behavior with "acpi_osi=Linux"

As this was the only entry, delete acpi_osl_dmi_table[].
