drm/i915/pm: drop intel_suspend_hw()
All intel_suspend_hw() does is clear PCH_LP_PARTITION_LEVEL_DISABLE bit
in SOUTH_DSPCLK_GATE_D for LPT LP. intel_suspend_hw() gets called from
i915_drm_suspend().
However, i915_drm_suspend_late() calls
intel_display_power_suspend_late(), which in turn calls hsw_enable_pc8()
on HSW and BDW. The first thing that does is clear
PCH_LP_PARTITION_LEVEL_DISABLE bit in SOUTH_DSPCLK_GATE_D.
Remove the duplicated clearing of the bit, effectively delaying it from
i915_drm_suspend() to i915_drm_suspend_late(), and remove the
unnecessary intel_suspend_hw() function altogether.
