drm/i915/pps: Decouple pps delays from VBT struct definition

We currently lack a proper struct definition for the VBT power
squencing delays, and instead we use the same struct definition
(in intel_bios.h) for both the VBT layout and our driver side
state. Decouple those two things by moving the current struct
into intel_vbt_defs.h and adding a new one for the driver's use.
