mb/dell: Add Latitude E6220 (Sandy Bridge)

Mainboard is codenamed Vida. I do not physically have this board; it was
ported based on autoport output sent to me which I then manually
modified. This port has not been tested.

The EC is the SMSC MEC5055, which seems to be compatible with the
existing MEC5035 code. As with the other Dell systems with this EC, this
board is assumed to be internally flashable using an EC command that
tells it to pull the FDO pin low on the next boot, which also tells the
vendor firmware to disable all write protections to the flash [1].
