Factor out bulk transfer for VCHIQ_BULK_MODE_NOCALLBACK and VCHIQ_BULK_MODE_CALLBACK mode into a separate dedicated function bulk_xfer_callback_interruptible(). It is suffixed by "_interruptible" to denote that it can be interrupted and -EAGAIN can be returned. It would be up to the users of the function to retry the call in those cases. bulk_xfer_callback_interruptible() also takes in 'mode' parameter to differentiate between VCHIQ_BULK_MODE_NOCALLBACK and VCHIQ_BULK_MODE_CALLBACK, which then is directly passed to vchiq_bulk_xfer_queue_msg_interruptible() inside the function. Adjust the calls to vchiq-dev.c ioctl interface and vchiq_arm.c for the respective bulk transfers.

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.
