drm/i915: convert VLV IOSF SB interface to struct drm_device2025-05-13T07:26:45ZJani Nikulajani.nikula@intel.com2025-05-12T14:56:57Zurn:sha1:bd4d1856f5fe427ad20d54c57bd0f2724f7be47e
With users both in i915 core and display, struct drm_device is the
common denominator for the VLV IOSF SB users. Also use drm_device for
the helpers on the display side to keep the static inlines as simple as
possible.
We can drop a number of dependencies on i915_drv.h with this.

drm/i915: move VLV IOSF SB unit specific helpers under display2025-05-13T07:26:45ZJani Nikulajani.nikula@intel.com2025-05-12T14:56:56Zurn:sha1:8393253b850b6a5c62d4bb875b582e1582103db8
Now that all the VLV IOSF SB unit specific helper users are under
display, relocate the helpers themselves under display as
well. Resurrect the vlv_sideband.[ch] name for this. Make everything
except DPIO helpers static inlines, as their implementations are
trivial.
All of this considerably simplifies the xe compat header.

drm/i915: rewrite VLV IOSF SB unit specific read/write functions2025-05-13T07:26:45ZJani Nikulajani.nikula@intel.com2025-05-12T14:56:54Zurn:sha1:5c76b7178b511019c0c5f5544d9bfc4b9589f0d4
Rewrite the VLV IOSF SB unit specific helpers in terms of the new
generic read/write functions. They become even simpler than they were.
The DPIO get/put helpers need to get/put both DPIO units.
v2: get/put both DPIO units

Be more specific in the naming, and follow the existing function naming
pattern of vlv_iosf_sb_*() in the file.
