If it failed, leave it in the "off" state.

If a PCH pipe PLL is being used by transcoder C, don't disable it.

This just causes unnecessary set_config calls.

We restore the CRTC, encoder, and connector configurations, but if the
mode set failed, the attached display may have been turned off, so we
need to try set_config again to restore things to the way they were.

Belongs in PCH enable instead. The duplication is worrying and the
specs explicitly list transcoder select *after* actual PLL enable, which
doesn't occur until later.

The watermark reg for the third pipe is in an unusual offset; add
support for it and set watermarks for 3 pipe configs.

At the point where we check, we can't do much about the failure, but it
can aid debugging. Note that the auto-train override bit will be reset
as part of normal mode setting with this patch if a pipe ever does get
stuck, but that's consistent with the workaround for CPT provided by the
hardware team. This patch helped catch the fact that the pipe wasn't
running in the !composite sync FDI case on my IVB SDV, so has already
shown to be useful.

Transcoder A will always use PLL A and transcoder B will use PLL B. But
transcoder C could use either, so always mask the select bits off before
or'ing in a new value.

The cursor regs have moved around, add the offsets and new macros for
getting at them.
