gt: allow for i2c bus to move around a little

Browse Source 
Unfortunately GT has alot of i2c buses, the second lot of designware buses can
turn up after the i915 i2c buses but since they all have the same name, we do a
dumb check to see if they are 5/6 or 9/10. Hopefully future kernel/firmware
will let us do something smarter.
