Fix default VGA console on SN platforms. Since SN firmware does not pass enough ACPI information to identify VGA cards and the associated legacy IO/MEM addresses, we rely on the EFI PCDP table. Since the linux pcdp driver is optional (and overridden if console= directives are used) SN duplicates a portion of the pcdp scan code to identify if there is a usable console VGA adapter. Additionally, dup necessary pcdp related structs to avoid dragging drivers/pcdp.h into a more public location.
