This patch adds the interrupt handling module, in kfd_interrupt.c, and its
related members in different data structures to the amdkfd driver.
The amdkfd interrupt module maintains an internal interrupt ring per amdkfd
device. The internal interrupt ring contains interrupts that needs further
handling. The extra handling is deferred to a later time through a workqueue.
There's no acknowledgment for the interrupts we use. The hardware simply queues
a new interrupt each time without waiting.
The fixed-size internal queue means that it's possible for us to lose
interrupts because we have no back-pressure to the hardware.
v3:
Move amdkfd from drm/radeon/ to drm/amd/
Change device init
Made sure spin lock is taken only if init is complete
Moved bool field to the end of the structure
