From: Siva Rebbagondla <siva.rebbagondla@xxxxxxxxxxxxxxxxxx>
BT frames are passed through coex and hal modules to BUS.
After firmware is loaded, based on the operating mode CARD
READY frame comes for each protocol. When BT card ready is
received, BT attach is called.
Protocol operations are exchanged between the modules
at initialization time.
