Avoid usage of global zynqmp_dpsub.dma_enabled flag in DPSUB layer context. This flag signals whether the driver runs in DRM CRTC or DRM bridge mode, assuming that all display layers share the same live or non-live mode of operation. Using per-layer mode instead of global flag will simplify future support of the hybrid scenario. Remove redundant checks in DMA request/release contexts as zynqmp_disp_layer.info is well-defined for all layer types, including the correct number of DMA channels required for each particular layer.

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.
