mb/hp: Add new port for compaq_8300_elite_usdt

New port based on autoport.

This board has NPCD379 SuperIO, which seems similar to NPCD378.
So I added the SuperIO code from hp8200sff. Seems to work fine.
Fan speeds stay low when idling. (Without this, they went 100%)

The following is tested and is working:
* Native raminit with both DIMMs
* Libgfxinit textmode and framebuffer on both DisplayPorts and VGA
* External USB2 and USB3 ports: they all work
* USB 3.0 SuperSpeed on Linux-libre (rear, 4 ports)
* Ethernet
* Mini-PCIe WLAN
* SATA: 2.5" SSD and optical drive bay
* Booting Live Linuxes from DVD and USB with SeaBIOS 1.16.1
* PS/2 keyboard and mouse
* S3 suspend and resume, wake using USB keyboard
* Headphone output, line out, internal speaker
* Wake on LAN
* Rebooting
* CMOS options & nvramcui

Untested:
* mSATA slot. The SATA port needs to be enabled on devicetree
  too, but I'm unable to test due to lack of hardware
* Line in, mic input
* MXM graphics card
* EHCI debug

Not working:
* Mini-PCIe USB: I couldn't get it working on vendor BIOS either, so
  maybe it just isn't present
* PS/2 keyboard wake from S3
