We previously assumed (incorrectly a lot of the time) that PTIMER would
be programmed at a frequency which'd give its 64-bit timestamps in
nanoseconds.

By programming PTIMER ourselves, we avoid this problem.

Not cleaning after alloc failure would result in crash on destroy,
because nouveau_sgdma_clear assumes "ttm_alloced" to be not null when
"pages" is not null.

If the bios or OS sets the pci max read request size to 0 or an
invalid value (6,7), it can result in a hang or slowdown.  Check
and set it to something sane if it's invalid.

On some Power rv100 cards, we have no ATY OF table, but we have
no combios table either, and hence we refuse all modes on VGA-0
since we end up with a 0 max pixel clock.
