Add a new ioctl to vt to make it possible to export RGB offsets
set by vt drivers. This is needed to fix colors on X and Mesa
on some machines, especially on modern PowerPC64 BE ones.

With the appropriate changes in SCFB, to use this ioctl to find
out the correct RGB offsets, this fixes wrong colors on Talos II
and Blackbird, when used with their built-in video cards.

VOP_STRATEGY() requires locked vnode.  Note that we lock the swap vnode
while pages are busy, but this would only cause real LoR if pages belong
to the swap vnode, which must not be the case for correct use.

With MIPS' retirement we now have more discontinued architectures than
supported ones, making the table somewhat unclear.  Split the table in
two.

Currently agp(4) effectively assumes that only one driver instance
exists, as the generic attach routine attempts to create /dev/agpgart
and triggers a panic if it already exists.  Instead, handle this
situation by creating /dev/agpgart<unit> and making /dev/agpgart an
alias of /dev/agpgart0 for compatibility.

Instead of returning 0xffs some controllers, such as Layerscape generate
an external exception when someone attempts to read any register
of config space of a non-existing device other than PCIR_VENDOR.
This causes a kernel panic.
Fix it by bailing during device enumeration if a device vendor register
returns invalid value. (0xffff)
Use this opportunity to replace some hardcoded values with a macro.

I believe that this change won't have any unintended side-effects since
it is safe to assume that vendor == 0xffff -> hdr_type == 0xffff.
