mainboard/hp: Add HP Elitebook 8470p

The code is based on the code generated by autoport.

The EHCI debug port is between the DP port and eSATA port.
The serial port on dock can also be used for debugging.

The model with discrete graphics is not tested.

Tested and work:
- memory: 0+4G, 4G+0, 4G+4G
- Linux (Arch Linux with kernel 4.10.6) boot from SeaBIOS payload
  with native graphics init
- WLAN
- keyboard, trackpoint and touchpad
- USB
- serial port on dock
- fan control
- AC and battery status

(EC) blobs:

This laptop uses SMSC KBC1126 EC, and there are two blobs needed by it.

You can use the tools in util/kbc1126/ to extract them and insert them
to the coreboot image using the following configuration:

  -> Chipset
    -> Add firmware images for KBC1126 firmware
