0bf1e5a852 drm/i915/pps: move pps code over from intel_display.c and refactor 
intel_display.c has some pps functions that belong to intel_pps.c. Move
them over.

While at it, refactor the duplicate intel_pps_init() in intel_display.c
into an orthogonal intel_pps_setup() in intel_pps.c, and call it earlier
in intel_modeset_init_nogem().

bcdf0f71b0 drm/i915/pps: rename vlv_init_panel_power_sequencer to vlv_pps_init 
This function is a bit of an outlier, but try to change to a name that
is more in line with the rest of the intel_pps functions. No functional
changes.

07eb5b1f17 drm/i915/pps: rename intel_power_sequencer_reset to intel_pps_reset_all 
Follow the usual naming pattern for functions. "reset all" because it
iterates over all DP encoders. No functional changes.

73bb78b5ba drm/i915/pps: abstract intel_pps_encoder_reset() 
Add an "encoder reset" call to hide some more pps functions, and clean
up the callers. A minor functional change is not holding the pps lock
across the whole operation in intel_dp_encoder_reset, but instead doing
it in two steps.

v2: rename intel_pps_reinit to intel_pps_encoder_reset for clarity

c520869ac4 drm/i915/pps: add higher level intel_pps_init() call 
Add a new init call to be called only once, unlike some of the other
various init calls. This lets us hide more functions within

abad6805ee drm/i915/pps: abstract panel power sequencer from intel_dp.c 
In a long overdue refactoring, split out all panel sequencer code from
intel_dp.c to new intel_pps.[ch].

The first part is mostly just code movement as-is, without cleanups or
functional changes.

We need to add a vlv_get_dpll() helper to get at the vlv/chv dpll from
pps code.

v2: Rebase.
