drm/i915: Move per-platform power well hooks to intel_display_power_well.c
Move the implementation of platform specific power well hooks to
intel_display_power_well.c, to reduce the clutter in
intel_display_power.c.
The locking of all the power domain/power well state is handled in the
power domain functions in intel_display_power.c using
i915_power_domains::lock. This patch also moves the
chy_phy_powergate_ch/lanes() functions to intel_display_power_well.c
which borrow the same lock to protect the DISPLAY_PHY_CONTROL register
state, which the HW uses both for toggling power wells and power gating
PHY lanes.
No functional change.
v2:
- Clarify in the commit log why CHV functions using the
i915_power_domains::lock were moved, while others locking the power
domain/well state were kept in intel_display_power.c . (Jouni)
- Move forward declaration of chv_phy_powergate_ch/lanes() to
intel_display_power_well.h .
