Add support to request uplink MUMIMO trigger stats from firmware through HTT stats type 27. These stats give information about bandwidth, RSSI of signal received, dB mean of pilots received, etc., of all users. Note: MCC firmware version WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4 does not support tags HTT_STATS_RX_PDEV_UL_TRIG_STATS_TAG(94) and HTT_STATS_RX_PDEV_UL_OFDMA_USER_STATS_TAG(95), currently.

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.
