Replace the deprecated[1] use of 1-element arrays in struct sgmap, struct sgmap64, struct sgmapraw, struct user_sgmap, and struct user_sgmap64 with modern flexible arrays. Additionally remove struct user_sgmapraw as it is unused. The resulting binary output differences from this change are limited only to stack space consumption of the smaller "srbu" variable in aac_issue_safw_bmic_identify() and aac_get_safw_ciss_luns(), as well as the smaller associated pair of memcpy()s in aac_send_safw_bmic_cmd(). Artificially growing the size of srbu back to its prior size removes all binary differences[2]. As an aside, after studying the aacraid driver code I wonder how aac_send_wellness_command() ever works. It is reporting a size 4 bytes too small for what it has constructed in memory in the DMA region: sgentry64 is size 12, whereas sgentry is size 8. Perhaps the hardware doesn't care. (Regardless, it is unchanged by this patch.)

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.
