openchrome: Fix a performance regression.
...
Unichrome's don't like small command submissions, so pad the
command stream with dummy data.
Also use 0x40c as pause address register instead of 0x418, as
reading the latter seems to sometimes stall the PCI bus until
the AGP command reader has completed a cycle.
