mb/dell: Add Latitude E6220 (Sandy Bridge)
Mainboard is codenamed Vida. 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. The VBT was obtained using intelvbttool while running version A14 (latest available version) of the vendor firmware. Tested and found to boot as part of a libreboot build based on upstream coreboot commit b7341da191 with additional patches, though these do not appear to affect SNB/IVB. The base E6430 patch was tested against coreboot main. 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].
