Currently the driver halts the device CPU in the halt engines function,
which halts all the engines of the ASIC. The problem is that if later on we
stop the reset process (due to inability to clean memory mappings in time),
the CPU will remain in halt mode. This creates many issues, such as
thermal/power control and FLR handling.
Therefore, move the halting of the device CPU to the very end of the reset
process, just before writing to the registers to initiate the reset. In
addition, the driver now needs to send a message to the device F/W to
disable it from sending interrupts to the host machine because during halt
engines function the driver disables the MSI/MSI-X interrupts.

This patch provides a workaround for a H/W bug in Goya, where access to
RAZWI from TPC can cause PCI completion timeout.
The WA is to use the device MMU to map any unmapped DRAM memory to a
default page in the DRAM. That way, the TPC will never reach RAZWI upon
accessing a bad address in the DRAM.
When a DRAM page is mapped by the user, its default mapping is
overwritten. Once that page is unmapped, the MMU driver will map that page
to the default page.
To help debugging, the driver will set the default page area to 0x99 on
device initialization.

This patch adds support for receiving events from Goya's control CPU and

Goya's PCI controller supports up to 8 MSI-X interrupts, which only 6 of
them are currently used. The first 5 interrupts are dedicated for Goya's
DMA engine queues. The 6th interrupt is dedicated for Goya's control CPU.
The DMA queue will signal its MSI-X entry upon each completion of a command
buffer that was placed on its primary queue. The driver will then mark that
CB as completed and free the related resources. It will also update the
command submission object which that CB belongs to.
There is a dedicated event queue (EQ) between the driver and Goya's control
CPU. The EQ is located on the Host memory. The control CPU writes a new
entry to the EQ for various reasons, such as ECC error, MMU page fault, Hot
temperature. After writing the new entry to the EQ, the control CPU will
trigger its dedicated MSI-X entry to signal the driver that there is a new
entry in the EQ. The driver will then read the entry and act accordingly.

For each external queue there is a completion queue, which is located on

Host memory while internal QMANs are located on the on-chip memory.
