drm/format-helper: Cache buffers with struct drm_format_conv_state
Hold temporary memory for format conversion in an instance of struct
drm_format_conv_state. Update internal helpers of DRM's format-conversion
code accordingly. Drivers will later be able to maintain this cache by
themselves.
Besides caching, struct drm_format_conv_state will be useful to hold
additional information for format conversion, such as palette data or
foreground/background colors. This will enable conversion from indexed
color formats to component-based formats.
v5:
* improve documentation (Javier, Noralf)
v3:
* rename struct drm_xfrm_buf to struct drm_format_conv_state
(Javier)
* remove managed cleanup
* add drm_format_conv_state_copy() for shadow-plane support
