ACPI: bus: Indicate support for more than 16 p-states thru _OSC
The code responsible for parsing the available p-states should have no problems handling more than 16 p-states. Indicate this by setting bit 10 ("Greater Than 16 p-state support") when evaluating _OSC. Signed-off-by: Armin Wolf <W_Armin@gmx.de> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
