drm/i915: Initialize dkl_phy spin lock from display code path

drm/i915: Initialize dkl_phy spin lock from display code path

Start moving the initialization of display locks from
i915_driver_early_probe().
Display locks should be initialized from display-only code paths.

It was also agreed that if a variable is only used in one file, it
should be initialized only in that file, so intel_dkl_phy_init() was
added.

v2:
- added intel_display_locks_init()

v3:
- rebased

v4:
- dropped intel_display_locks_init()

v5:
- moved intel_dkl_phy_init() to the beginning of file
