ice: Initialize PF and setup miscellaneous interrupt
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.
