[PATCH v5 0/7] wcn36xx: Add a set of helpers to enable VHT parameter passing

[Bryan O'Donoghue <bryan.odonoghue@linaro.org>]

This series is two in a set of seven to add support for wcn3680 at 802.11ac
data-rates.

V5:
- Fixes -W=1 warning caught in later patches by kernel build robot
  I'm still declaring these functions standalone for the purposes of
  granularity and bisectability, a later patch makes them static.

V4:
- No functional change.

V3:
- Enables MU-MIMO bits in wcn36xx_smd_set_sta_vht_params()
- Adds a set of helper functions. In the previous set these unused
  declarations would cause a warning during compile because they were
  declared static with the intention to add code later on to use them.

  To resolve that, I do not declare the functions static. Static
  declaration is done in a later patch after the functions have been used.

- There are two good reasons for this:
  1. Granularity. I think its important and useful to have a patch per
     function that clearly sets out what it does and why.
  2. Patch size. Declaring seven functions at the time of their first
     use is not good practice.

I think maintaining patch granularity is a good enough reason to not squash
these commits down. It is pretty trivial to declare the functions static
later on without generating compile warnings in the interregnum.

V2:
This set makes a series of modifications to enable passing of an extended
V1 data-structure to the firmware.

A series of of helper functions are added to facilitate the setup.

The final step in the process is enabling the extended data-structure
parameter passing for the wcn3680 only.

Only a firmware that is capable of 80211.ac will accept the larger V1
messages and only after explicitly enabling the DOT11AC firmware feature
bit.

- No functional difference from V1 for these patches
  Breaking into smaller chunks to enable easier review/merging
