Vinayak Chettimada d5d473b0f8 Bluetooth: Controller: replace work with mayfly
This commit introduces a very light-weight and lock-less
scheduling of the Controller's deferred function calls
called the Mayfly.

Earlier work implementation used in the Controller had an
O(n) to schedule a function in a linked list that used IRQ
lock during modification of the linked list in the
Controller's ISR executions.

Mayfly is a compile time configurable matrix of queues
where an execution context-safe queue exists between two
execution context, one being the caller and the second
being the callee. Callee(s) are run in a software interrupt
but can also be run in an OS thread.

There are minor clean ups too in this commit related to
folder structure.

Vinayak Chettimada e9b818e763 Bluetooth: Controller: Fix suspicious use of sizeof
Fix Coverity, sizeof not portable, defect; by explicitly
using sizeof(void *).

suspicious_sizeof:
Passing argument mem_head of type void ** and argument 4U
/* sizeof (mem_head) */ to function memcpy is suspicious.
In this case, sizeof (void **) is equal to sizeof
(void *), but this is not a portable assumption.

Vinayak Chettimada 26f6b71a8e Bluetooth: Controller: Fix incorrect irq priority check
External interrupts are indexed from value 16, wherein
0 to 15 are ARM cortex M exceptions. Fixed code in
_irq_is_priority_equal to fetch correct external
interrupt line ISR priority.
