drm/i915: add PLL sharing support to handle 3 pipes
Add two new fields to the intel_crtc struct for 3 pipe support: no_pll
and use_pll_a. The no_pll field is only set on the 3rd pipe to indicate
that it doesn't have a PLL of its own and so shouldn't try to write the
main PLL regs. The use_pll_a field controls which PLL pipe 3 will
share, A or B. The core code will try to share PLLs with whichever pipe
has the same timings, rejecting the mode set if none is found. This
means that pipe 3 must always be set after one of the other pipes has
been configured with real PLL settings.
