Oleksij Rempel e9b6151868 platform/x86: asus-wmi: try to set als by default 
some laptops, for example ASUS UX330UAK, have brocken als_get function
but working als_set funktion. In this case, ALS will stay turned off.

             Method (WMNB, 3, Serialized)
            {
	    ...
               If (Local0 == 0x53545344)
                {
		...
                    If (IIA0 == 0x00050001)
                    {
                        If (!ALSP)
                        {
                            Return (0x02)
                        }

                        Local0 = (GALS & 0x10)    <<<---- bug,
                                                    should be: (GALS () & 0x10)
                        If (Local0)
                        {
                            Return (0x00050001)
                        }
                        Else
                        {
                            Return (0x00050000)
                        }
                    }

             .....
                If (Local0 == 0x53564544)
                {
		...
                    If (IIA0 == 0x00050001)
                    {
                        Return (ALSC (IIA1))
                    }

                  ......
                    Method (GALS, 0, NotSerialized)
                    {
                        Local0 = Zero
                        Local0 |= 0x20
                        If (ALAE)
                        {
                            Local0 |= 0x10
                        }

                        Local1 = 0x0A
                        Local1 <<= 0x08
                        Local0 |= Local1
                        Return (Local0)
                    }

Since it works without problems on Windows I assume ASUS WMI driver for Win
never trying to get ALS state, and instead it is setting it by default to ON.

This patch will do the same. Turn ALS on by default.
