Add support for PMCI-based flash access path and N6000 sec update support. Access to flash staging area is different for N6000 from that of the SPI interfaced counterparts. Introduce intel_m10bmc_flash_bulk_ops to allow interface specific differentiations for the flash access path for sec update and make m10bmc_sec_read/write() in sec update driver to use the new operations. The .flash_mutex serializes read/read. Flash update (erase+write) must use ->lock/unlock_write() to prevent reads during update (reads would timeout on setting flash MUX as BMC will prevent it). Create a type specific RSU status reg handler for N6000 because the field has moved from doorbell to auth result register. If a failure is detected while altering the flash MUX, it seems safer to try to set it back and doesn't seem harmful. Likely there are enough troubles in that case anyway so setting it back fails too (which is harmless sans the small extra delay) or just confirms that the value wasn't changed.

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.
