mb/hp: Add new port for compaq_8300_elite_usdt

New port based on autoport.

Autoport worked with minor tweaks, but fan speeds went almost
immediately to the maximum. They are controlled by the NPCD379
Super I/O which isn't supported by coreboot.

But coreboot already has code for NPCD378,
which HP Compaq 8200 SFF makes use of.

So SuperIO configuration was copied from the 8200 SFF port.
It seems to work without any issues in "normal" use.
Most importantly, fan speed control seems to work correctly.

However this means that some of the SuperIO LDNs may be configured
incorrectly. See the comments on Gerrit for more information.

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
* GRUB (with Libreboot config)
* 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
