Implements gamma tables for OMAP4, OMAP5, and dra7xx SoCs and adds a
work-a-round for errata that may break LCD1 channel if gamma tables
are in use.
Also adds new drm_crtc_enable_color_mgmt() as suggested[1] by Daniel
Vetter and get rid of the old drm_helper_crtc_enable_color_mgmt(). I
have not tested the change to i915 driver, only compiled it, but
functionally it should be exactly the same.

Changes from v3 to v4
- "drm/omapdrm: Add gamma table support to DSS dispc"
- use interpolation code in dispc_mgr_set_gamma() to produce default lut
- restore default lut table if NULL is given as gamma lut table
- "drm/omapdrm: Implement gamma_lut atomic crtc property"
- attach gamma_lut_property and gamma_lut_size_property to crtc if
gamma tables are supported
- restore default table if gamma lut property is deleted
- Adds:
- drm: Add drm_crtc_enable_color_mgmt()
- drm/omapdrm: Use drm_crtc_enable_color_mgmt() to enable gamma properties
- drm/i915: Use drm_crtc_enable_color_mgmt()
- drm: Remove obsolete drm_helper_crtc_enable_color_mgmt()
Changes from v2 to v3
- "drm/omapdrm: Add gamma table support to DSS dispc"
- fix dispc_init_gamma_tables() to always return an int
- omap54xx_dispc_feats initializes .has_gamma_table not .has_gamma_tables
- "drm/omapdrm: Work-a-round for errata i734 (LCD1 Gamma) in DSS dispc"
- work-a-round -> workaround
- Do not mention LOADMODE in description
- dma_alloc_writecombine returns NULL on error
- fix last wrong instrance of LCD output gating register
- improve comment for framedone busy wait
- add {} around busy loop's while statement
Changes from v1 to v2
- Drop "drm/omapdrm: omap_modeset_init: Separate crtc id and plane id indexing"
- "drm/omapdrm: Add gamma table support to DSS dispc"
- Address Tomi's comments here: https://patchwork.kernel.org/patch/9128629/
- "drm/omapdrm: Work-a-round for errata i734 (LCD1 Gamma) in DSS dispc"
- Address Tomi's comments here: https://patchwork.kernel.org/patch/9128633/
