src/mainboard/dell/inspiron_*: Add Support for Dell Inspiron 620 & 3847

Add Initial Support for Dell Inspiron 620 and Dell Inspiron 3847. (using Autoport)
On my 620, UEFI freezes up for ~5m then boots, my 2nd RAM slot doesn't get recognized (even in stock rom, although stock doesn't boot up and gives freeze or POST), else everything works from what I can tell (could mean my board is partially damaged)
On my 3847, everything works, UEFI doesn't freeze up, but my external GPU doesn't work (internal does), it is a NVIDIA GEFORCE GT 710 and cannot figure out how to default to it, though the linux driver works fine with it (windows was also untested on both machines).
NOTE: As of 2022, I need to get a replacement 620 MB, due to the fact that the BIOS chip fried. My 3847 Works fine though. Someone also had the same freezing issue on a SNB in coreboot discord, which later upgraded to IVY Bridge, could also need a SATA Patch, not known yet until a get a new MB.
