skylake: Add SD card device to configure card detect GPIO

Add a PCI driver for the skylake SD card device and have it generate
    an entry in the SSDT for the card detect GPIO if it is provided by the
    mainboard in devicetree.

This sets up a card detect GPIO configuration that will trigger an
    interrupt on both edges with a 100ms debounce timeout and can wake the
    SD controller from D3 state.

The GpioInt() entry is bound to the "cd-gpio" device property which will
    be consumed by the kernel driver.

The resulting ACPI output in the SSDT will be combined with the SDXC
    device declaration in the DSDT.

Example:

Scope (_SB.PCI0.SDXC)
    {
      Name (_CRS, ResourceTemplate () {
        GpioInt (Edge, ActiveBoth, SharedAndWake, PullNone, 10000,
                 "\_SB.PCI0.GPIO", 0, ResourceConsumer) { 35 }
      })
      Name (_DSD, Package () {
        ToUUID ("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
        Package () {
          Package () { "cd-gpio", Package () { _SB.PCI0.SDXC, 0, 0, 1 } }
        }
      })
    }
