FM-HAL: Add support for FM Core functionalities

FM-HAL Layer contains the core FM Functionality required
for carrying out various FM operations such as FM Enable,
FM Tune, FM Seek, FM Search, FM Disable etc..
FM-HAL layer interacts with the FM-HCI layer for sending
commands and receiving events to and from Controller.
