Make skl_ddb_allocation_overlaps() useful for other callers besides skl_update_crtcs(). We'll need it to do plane updates as well. And while we're here we can reduce the stack utilization a bit by noting that each struct skl_ddb_entry is 4 bytes whereas a pointer to one is 8 bytes (on 64bit). So we'll switch to an array of structs from the array of pointers we used before.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
