qcacmn: Introduce constants for 160MHz precac tree

Browse source 
Introduce constants for building the 160MHz precac tree.

Add support to insert the 165MHz channel into the precac tree.

The precac entry is not restricted to be 80MHz bandwidth, it can be
20/40/80/160/165MHz, therefore introduce a new variable bw to
accommodate different bandwidths.
