platform/x86: lg-laptop: Add support for the HDAP opregion field

Browse source

Various LG notebooks have a special field called "HDAP" inside
the ACPI operation region handled by the lg-laptop driver:

	Field (XIN1, AnyAcc, Lock, Preserve)
	{
		DMSG,   8,
		HDAP,   8,
		Offset (0x10),
		P80B,   8,
		P81B,   8,
		P82B,   8,
		P83B,   8,
		P84B,   8,
		P85B,   8,
		P86B,   8,
		P87B,   8,
		Offset (0x3E8),
		PMSG,   1600
	}

This field is set to 1/0 when the HD audio device is enabled/disabled
using the _PS0/_PS3 ACPI control methods. Add support for this field
to avoid printing warning messages when AML bytecode writes data
into it.
