drm/fb-helper: separate the fb_setcmap helper into atomic and legacy paths
The legacy path implements setcmap in terms of crtc .gamma_set.
The atomic path implements setcmap by directly updating the crtc gamma_lut
property.
This has a couple of benefits:
- it makes the redundant fb helpers .load_lut, .gamma_set and .gamma_get
completely obsolete. They are now unused and subject for removal.
- atomic drivers that support clut modes get fbdev support for those from
the drm core. This includes atmel-hlcdc, but perhaps others as well?
