ENGR00156300 - EPDC fb: Move ISR code to work Q & replace spinlocks with mutexes

- Move the majority of code from the IRQ handler routine into a workqueue
routine.  This should improve system interrupt latency.
- Change the spin_lock protecting EPDC queues into a mutex and change all
associated spin_lock calls into mutex calls.
