wcn36xx: Fix reported 802.11n rx_highest rate wcn3660/wcn3680

[ Upstream commit 3b9fb6791e7113679b1eb472e6ce1659e80f5797 ]

Qualcomm's document "80-WL007-1 Rev. J" states that the highest rx rate for
the WCN3660 and WCN3680 on MCS 7 is 150 Mbps not the 72 Mbps stated here.

This patch fixes the data-rate declared in the 5GHz table.

hardware")
