This series is six in a set of seven to add support for wcn3680 at 802.11ac
data-rates.
These two commits have been moved later in the set of commits so that the
patches to enable advertisement of VHT capabilities happen after all of the
supporting code has been comitted.
Changes from V2:
- Rename "wcn36xx: Add ieee802.11 VHT flags" to "wcn36xx: Advertise
ieee802.11 VHT flags"

wcn36xx: Add VHT rates to wcn36xx_update_allowed_rates()

From: Bryan O'Donoghue <[email protected]>
This commit adds VHT rates to the wcn36xx_update_allowed_rates() routine.
Thus allowing the driver to latch the declared rates and transmit them to
the firmware in the same way as other 80211.n rates are.

From: Bryan O'Donoghue <[email protected]>
This patch adds ieee802.11 VHT flags for the wcn3680b.
- RX_STBC1
- SU Beamformee
- MU Beamformee
- VHT80 SGI
- Single spatial stream
RX LDPC is declared as supported in the datasheet but not enabled at this
time.
After this patch is applied an AP should see the wcn3680 as an 802.11ac
capable device.
