As the F/wW is the first to detect out of sync event, a new event is
added to notify the driver on such event. In which case the driver
performs hard reset.

The goya_non_fatal_events array actually contains all the possible events
the driver can receive from the F/W. Therefore, use a proper name
for the array.
The patch also adds missing event Ids to the goya_async_event_id enum.

This patch adds the H/W queues module and the code to initialize Goya's
various compute and DMA engines and their queues.
Goya has 5 DMA channels, 8 TPC engines and a single MME engine. For each
channel/engine, there is a H/W queue logic which is used to pass commands
from the user to the H/W. That logic is called QMAN.
There are two types of QMANs: external and internal. The DMA QMANs are
considered external while the TPC and MME QMANs are considered internal.
For each external queue there is a completion queue, which is located on
the Host memory.
The differences between external and internal QMANs are:
1. The location of the queue's memory. External QMANs are located on the
Host memory while internal QMANs are located on the on-chip memory.
2. The external QMAN write an entry to a completion queue and sends an
MSI-X interrupt upon completion of a command buffer that was given to
it. The internal QMAN doesn't do that.
