intel/dcp847ske: Add Intel NUC DCP847SKE

https://ark.intel.com/products/71620/Intel-NUC-Board-DCP847SKE

Created using autoport and manual edits.
mainboard_fill_pei_data copied and adjusted from samsung/lumpy.

Tested:
- RAM slots with 2x4GB Kingston KVR1333D3S9/4G (DDR3-1333 1.5V).
- RAM slots with 2x4GB Kingston KVR16LS11/4G (DDR3L-1600 1.35V).
- SeaBIOS stable payload.
- Linux 4.13.14 payload.
- Booting into Linux 4.13.14 with Debian/unstable installed on the
  internal mSATA slot.
- Non-native raminit (works).
- Native raminit
  - KVR1333D3S9 doesn't work.
  - KVR16LS11 only works at 1.5V.
- Native VGA init, HDMI port detection with libgfxinit.
- Basic ACPI functions (power button event; power-off; reboot).
- Suspend to RAM and resume works.
- PCIe WLAN in half-minicard slot.
- USB device in half-minicard slot.
- PCIe device in full-minicard slot.
- mSATA device in full-minicard slot.
- Fan spins up/down in response to CPU load.

Known issues:
- Native raminit fails timC calibration with the RAM I have.
- Technical Product Specification mentions overcurrent protection
  for back panel and front panel USB connectors, but I haven't
  been able to trigger it with either native fw or coreboot
  (tried up to 2.5A load).

Untested:
- USB debug port.
