Add controller logs to kdump. Driver allocates DMA memory and communicates this address to FW. In the event of system crash, host driver notifies the firmware about the crash and firmware posts all the necessary logs in the pre-allocated host buffer for firmware debugging. Once firmware notifies the completion of the log uploading to the host memory and host continues with the OS crash dump saving. This is a "feature" driven capability and is backward compatible with existing controller FW. Rename some prefixes for OFA (Online-Firmware Activation ofa_*) buffers to host_memory_*. So, not a lot of actual functional changes to smartpqi_init.c, mainly determining the memory size allocation. Added a function to notify the controller to copy debug data into host memory before continuing kdump. Most of the functional changes are in smartpqi_sis.c where the actual handshaking is done.

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.
