Define a QCA vendor command to validate encryption engine

This command carries 802.11 header and payload along with key (TK) and
PN for encryption/decryption purpose. Firmware/driver encrypts/decrypts
the given data and sends to userspace as a response to the command. User
space component can validate the data received from the driver to unit
test the hardware's encryption engine.
