drm/i915/bxt: BUNs related to port PLL
This patch contains changes based on 2 updates to the spec:
Port PLL VCO restriction raised up to 6700.
Port PLL now needs DCO amp override enable for all VCO frequencies.
v2: Sonika's review comment addressed
- dcoampovr_en_h variable not required
Based on a discussion with Siva, the following changes have been made.
- replace dco_amp var with #define BXT_DCO_AMPLITUDE
- set pll10 in a single assignment
v3:
Move DCO amplitude default value to i915_reg.h. Suggested by Siva.
