When pci_find_class() fails to find a device, it returns -ENODEV.
But now we check the return value against -1. Fix it.

We cannot use this driver when running from EFI as we have no direct hardware
access. In fact coreboot uses a different driver which uses tables provided
by coreboot. So far it does not seem possible to use a normal video driver
when booting from EFI.

Per PCI spec, VGA device reports its class as standard 030000h in
its configuration space, so we can use it to determine if we need
run option rom instead of testing the supported vendor/device ids.

Since we must run a PCI BIOS ROM, and this can take a calamitous amount of
time, measure it using bootstage.

If the BIOS emulator is not available, allow use of native execution if
available, and vice versa. This can be controlled by the caller.

Add a driver intended to cope with any VESA-compatible x86 graphics
adapter. It will not support ROMs which use OpenFirmware (Forth) since
there is no support for that in U-Boot. This means that MAC OS cards
will not work.
