drm/i915: add display engine uncore helpers
Add convenience helpers for the most common uncore operations with
struct drm_i915_private * as context rather than struct intel_uncore *.
The goal is to replace all instances of I915_READ(),
I915_POSTING_READ(), I915_WRITE(), I915_READ_FW(), and I915_WRITE_FW()
in display/ with these, to finally be able to get rid of the implicit
dev_priv local parameter use.
The idea is that any non-u32 reads or writes are special enough that
they can use the intel_uncore_* functions directly.
v2:
- rename the file intel_de.h
- move intel_de_wait_for_* there too
- also add de fw helpers
