drm/i915: extract intel_crt.h from intel_drv.h It used to be handy that we only had a couple of headers, but over time intel_drv.h has become unwieldy. Extract declarations to a separate header file corresponding to the implementation module, clarifying the modularity of the driver. Ensure the new header is self-contained, and do so with minimal further includes, using forward declarations as needed. Include the new header only where needed, and sort the modified include directives while at it and as needed. No functional changes.

drm/i915: Only include i915_reg.h from .c files Several of our i915 header files, have been including i915_reg.h. This means that any change to i915_reg.h will trigger a full rebuild of pretty much every file of the driver, even those that don't have any kind of register access. Let's delete the i915_reg.h include from all headers and add an explicit include from the .c files that truly need the register definitions; those that need a definition of i915_reg_t for a function definition can get it from i915_reg_defs.h instead. We also remove two non-register #define's (VLV_DISPLAY_BASE and GEN12_SFC_DONE_MAX) into i915_reg_defs.h to allow us to drop the i915_reg.h include from a couple of headers. There's probably a lot more header dependency optimization possible, but the changes here roughly cut the number of files compiled after 'touch i915_reg.h' in half --- a good first step.
