drm/i915: Merge the PPS register definitions
The PPS registers are pretty much the same everywhere, the differences being: - Register fields appearing, disappearing from one platform to the next: panel-reset-on-powerdown, backlight-on, panel-port, register-unlock - Different register base addresses - Different number of PPS instances: 2 on VLV/CHV/BXT, 1 everywhere else. We can merge the separate set of PPS definitions by extending the PPS instance argument to all platforms and using instance 0 on platforms with a single instance. This means we'll need to calculate the register addresses dynamically based on the given platform and PPS instance. v2: - Simplify if ladder in intel_pps_get_registers().
