Nicholas Chin fef29fc56f mb/dell: Add Latitude E5420 (Sandy Bridge)
Mainboard is Krug 14". I do not physically have this system; someone
with physical access to one sent me the output of autoport which I then
modified to produce this port. I was also sent the VBT binary, which was
obtained from `/sys/kernel/debug/dri/0/i915_vbt` while running version
A02 of the vendor firmware.

This was originally tested and found to be working as a standalone board
port in Libreboot, but this variant based port in upstream coreboot has
not been tested.

This can be internally flashed by sending a command to the EC, which
causes the EC to pull the FDO pin low and the firmware to skip setting
up any chipset based write protections [1]. The EC is the SMSC MEC5055,
which seems to be compatible with the existing MEC5035 code.
