Adds libreboot support for the Dell OptiPlex 3040 Micro based on the
OptiPlex 3050 Micro (same Skylake H110 PCH-H platform). Key differences:
DDR3L SODIMMs, Pentium G4400T-class CPUs (Skylake only), Realtek ALC3234
HDA, and Boot Guard neutralization via deguard.
Tested and booted on hardware.

Courtesy of Kat Inskip who ported this board.
Headphone output doesn't work at the moment, due to incorrect verb.
Intel VBT is also wrong. Both are taken from another board.
This will be amended later with the correct verb and VBT.

Using the same ME image as the 3050 Micro. This fixes the lack of a
backup download URL for the ME and speeds up boot time, since MRC
caching is working with ME (unlike SPS).
Unfortunately, since the MFS partition must be preserved, this does
mean we need a larger ME region than with me_cleaned SPS.
There really isn't anything functionally different. However,
this means one less patch is needed in lbmk.

Added t480s delta to deguard, for MFS config.
Updated coreboot/next to latest t480 patch set,
which includes t480s. This porting was done by
Mate Kukri.
also includes experimental t480s support
Also added a data.vbt file (not in the gerrit patch)
for the T480s.
I had to turn on 8254 legacy timer on t480s, otherwise
SeaBIOS would hang. Same issue I saw on OptiPlex 3050 Micro.
Minor issue:
On S3 resume, nvme0n1 for example got renamed to nvme0n2.
This caused a crash if running Linux from the nvme. I confirmed
this via live USB distro. So this port will need some tweaking
before it can be considered stable.
Also uses libgfxinit, which Mate recently fixed. I'm
going to enable libgfxinit on regular T480 next.
