mainboard/lenovo/g505s: Build in EC ASL support for KBD/AUX ports 

Rather than have Linux report:
 i8042: PNP: No PS/2 controller found. Probing directly.
and go off probing PNP config space, build in EC ASL for the
PS/2 keyboard and mouse.

The ASL explicitly passes these resources to the Linux to avoid
said probe.

ASL Details:
 PS/2 keyboard (PNP0303 at 0x60,0x64 irq 1 )
 PS/2 mouse    (PNP0F13 at 0x60,0x64 irq 12)
