Oded Gabbay 7cb5101ee0 habanalabs: prevent host crash during suspend/resume
This patch fixes the implementation of suspend/resume of the device so that
upon resume of the device, the host won't crash due to PCI completion
timeout.

Upon suspend, the device is being reset due to PERST. Therefore, upon
resume, the driver must initialize the PCI controller as if the driver was
loaded. If the controller is not initialized and the device tries to
access the device through the PCI bars, the host will crash with PCI
completion timeout error.

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.
