This patch continues the initialization flow as follows:
1) Allocate and initialize necessary fields (like vsi, num_alloc_vsi,
irq_tracker, etc) in the ice_pf instance.
2) Setup the miscellaneous interrupt handler. This also known as the
"other interrupt causes" (OIC) handler and is used to handle non
hotpath interrupts (like control queue events, link events,
exceptions, etc.
3) Implement a background task to process admin queue receive (ARQ)
events received by the driver.

A control queue is a hardware interface which is used by the driver
to interact with other subsystems (like firmware, PHY, etc.). It is
implemented as a producer-consumer ring. More specifically, an
"admin queue" is a type of control queue used to interact with the
firmware.
This patch introduces data structures and functions to initialize
and teardown control/admin queues. Once the admin queue is initialized,
the driver uses it to get the firmware version.
