mb/hp/t620: Add new mainboard HP T620 thin client
This commit adds support for HP T620, work was done during a coreboot hacking party! Board is AMD Fam16kb with laptop ram. Based off biostar/a68n-5200 port.
coreboot console works over serial COMA by default. Board is fanless, so no need for fan control.
TESTED: Boots SeaBIOS and to linux, NIC works, serial works.
Missing: - Audio verb table - PIRQs could be wrong (copied from other board) - ACPI could be wrong (copied from other board)
Caveat: Without VGA ROM there are no displays.
