Hans de Goede b5cc169919 ACPI / x86: Add Dell Venue 11 Pro 7130 touchscreen to always_present_ids 
The _STA method of the Venue 11 Pro 7130 touchscreen has this ugliness:

                Method (_STA, 0, NotSerialized)  // _STA: Status
                {
                    If ((SDS1 & One) == One)
                    {
                        If (RST1 == Zero)
                        {
                            Return (0x0F)
                        }
                        ElseIf (RST2 == Zero)
                        {
                            RST2 = One
                            TMRV = Timer
                        }
                        Else
                        {
                            Local0 = ((Timer - TMRV) / 0x2710)
                            If (Local0 > TMRI)
                            {
                                RST2 = Zero
                                RST1 = Zero
                            }
                        }
                    }
                    Else
                    {
                        Return (Zero)
                    }
                }

Whereby RST1 gets set by _SB.PCI0.GFX0.LCD.LCD1._ON, this means that
after RST1 has been set first _STA must be called to set TIMER and
then after enough time has elapsed _STA must be called twice more, once
to clear RST1 and once to finally return 0xf before the touchscreen will
show up. Which is just crazy.

This commit adds an always_present_ids entry for the SYNA7500 touchscreen
ACPI node, together with a DMI match for the Venue 11 Pro 7130, fixing the
touchscreen not working on this device.
