qca-wifi: Host Static Memory Optimization (in NSS offload mode)

Low memory profiles like 256M and 16M profiles support
only NSS Wi-Fi offload mode and HOST data path APIs are
not used.

Disable HOST data path APIs which are not used in both
NSS Wi-Fi offload mode and in HOST mode (in NSS offload mode)
