[Intel-gfx] [RFC 10/33] drm/i915/dp: use intel_de_*() functions for register access

[Jani Nikula <jani.nikula@intel.com>]

The implicit "dev_priv" local variable use has been a long-standing pain
point in the register access macros I915_READ(), I915_WRITE(),
POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW().

Replace them with the corresponding new display engine register
accessors intel_de_read(), intel_de_write(), intel_de_posting_read(),
intel_de_read_fw(), and intel_de_write_fw().

No functional changes.

Generated using the following semantic patch:
