drm/i915/hsw+: Add has_fuses power well attribute
The pattern of a power well backing a set of fuses whose initialization
we need to wait for during power well enabling is common to all GEN9+
platforms. Adding support for this to the HSW power well enable helper
allows us to use the HSW/BDW power well code for GEN9+ as well in a
follow-up patch.
v2:
- Use an enum for power gates instead of raw numbers. (Ville)
