wcn36xx: Add VHT fields to parameter data structures

wcn36xx: Add VHT fields to parameter data structures

In order to pass VHT parameters to wcn3680 we need to use a super-set of
the V1 data-structures with additional VHT parameters tacked on.

This patch adds the additional fields to the STA and BSS parameter
structures.

Since neither wcn3620 nor wcn3660 support VHT the size of the passed
message is fixed to the previous message length. Subsequent changes will
differentiate between wcn3620/wcn3660 and wcn3680 which does use the larger
message size.
