A side-effect of being able to use custom page allocations with the
sg_table is that it cannot reap the partially constructed scatterlist if
fails to allocate a page. So we need to call sg_free_table() ourselves
if sg_alloc_table() fails.

The original i965, including the revised G35 and Q35, requires an
alignment of 128K for the display surface with linear memory, so
increase the requirement from 64k for these chipsets. For the later
chipsets in the i965 family, only a 4k alignment is required. (So
long as we do not start performing asynchronous flips.)
Note the impact of this should be slight as on i965 we should be using a
tiled frontbuffer for anything up to a 4096x4096 display.
v2: compilation fixes and note that the docs do not exclude the G35 from
the extra alignment.

Unmask the bits for link training reporting before starting link
training. If stage 1 training finished before we unmask them, then we'd
spin around in a loop a few times until smashing on through. Which is
harmless, since training _did_ succeed, it just looks ugly in dmesg.

Since mode->clock is in kHz we should be checking against 2700000
instead of just 27000. This patch gets my x201s working again (well
working as well as it ever was anyway).
When looking for this I also noticed we set link_bw to 270000, but the
calculation is different. Does it also need to use kHz or we using
10kHz internally?
