Following the introduction of bridge_atomic_enable in the ingenic drm driver, the crtc is enabled between .prepare and .enable, if it exists. Add it so the backlight is only enabled after the crtc is, to avoid graphical issues. As we're moving the "sleep out" command out of the init sequence into .enable for the ABT, we need to switch the regmap cache to REGCACHE_FLAT to be able to use regmap_set_bits, given this panel registers are write-ony and read as 0.

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 Restructured Text 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.
