Merge the CRTC functions of ofdrm and simpledrm. Replace the code in each driver with the shared helpers. Set up callbacks with initializer macros. Ofdrm supports a gamma LUT, while simpledrm does not. So far ofdrm's LUT size has been hard-coded in the driver CRTC's atomic_check helper. Now pass the size of the LUT to the sysfb device. Ofdrm's custom atomic_flush is still required to apply changes to the LUT. Simpledrm passes a LUT size of 0, which disables the gamma LUT.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
