Ensure that imported buffers are properly mapped and unmapped in the same way as regular buffers to properly handle buffers during device's bind and unbind operations to prevent resource leaks and inconsistent buffer states. Imported buffers are now dma_mapped before submission and dma_unmapped in ivpu_bo_unbind(), guaranteeing they are unmapped when the device is unbound. Add also imported buffers to vdev->bo_list for consistent unmapping on device unbind. The bo->ctx_id is set in open() so imported buffers have a valid context ID. Debug logs have been updated to match the new code structure. The function ivpu_bo_pin() has been renamed to ivpu_bo_bind() to better reflect its purpose, and unbind tests have been refactored for improved coverage and clarity.

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.
