Rename GFX to IGPU and add this patch in your DSDT:

Device (IGPU)
{
Name (_ADR, 0x00020000)
Method (_DSM, 4, NotSerialized)
{
Store (Package (0x06)
{
"AAPL,snb-platform-id", 
Buffer (0x04)
{
0x00, 0x00, 0x01, 0x00
}, 

"hda-gfx", 
Buffer (0x0A)
{
"onboard-2"
}, 

"device-id", 
Buffer (0x04)
{
0x12, 0x01, 0x00, 0x00
}
}, Local0)
DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
Return (Local0)
}
