The BT Link Layer needs to get runtime in a timely manner to keep
connections alive and handle other time-critical tasks. This is achieved by
adding a separate thread for it with a meta-IRQ priority, which means it
can preempt other threads. The driver also has an RX thread that passes HCI
messages from the controller to the host stack. This can be a lower
priority cooperative thread, as it doesn't have strict timing requirements.

Link layer needs some fixing before hci driver can be minimally configured
and hence must revert conditional inclusion of core functionalities untill
new link layer is available.

Several driver setting were as defines in driver file which made hard to
change by application programmers. Fixed by adding
silicon labs specific Kconfig file for bluetooth driver configurations.
Also some cleaning for handling Kconfig conditional to conform
preferred style.
