v2: Prefer seq_puts to seq_printf by Paulo Zanoni.
v3: small changes like avoiding calling dp_to_dig_port twice as noticed by
Paulo Zanoni.
v4: Avoiding reading non-existent registers - noticed by Paulo
on first psr debugfs patch.
v5: Accepting more suggestions from Paulo:
* check sw interlace flag instead of i915_read
* introduce PSR_S3D_ENABLED to avoid forgeting it whenever added.

[danvet: Fix up debugfs output (spotted by Paulo) and rip out the
power well check since we really can't do that in a race-free manner,
so it's bogus.]
