qcacld-3.0: Add support to configure rate mask to cap phy rate

Bladeren bron 
The ini ratemask_type and ratemask_set can be used to limit
the maximum phy rate. The ratemask_type is used to select
the phy mode and the ratemask_set to select desired NSS and MCS.

It can be used to optimize link performance.
