The device can get into deadlock in case it use indirect mode for MSI
interrupts (multi-msi) and have hard-reset during interrupt storm.

To prevent that, always use direct mode which means single-msi mode.

The F/W will prevent the host from writing to the indirect MSI
registers to prevent any malicious user from causing this scenario.

As there are incorrect assumptions in which some of the
initialization and data path flows cannot sleep, most allocations
are being done using GFP_ATOMIC.
We modify the code to use GFP_ATOMIC only when realy needed, as
sleepable flow should use GFP_KERNEL.
In addition add a fallback to allocate memory using GFP_KERNEL,
once ATOMIC allocation fails.

After any reset (soft or hard) the device (the engines/QMANs) should
be idle. If they are not idle, fail the reset. If it is soft-reset,
the driver will try to do hard-reset automatically. If it is hard-reset,
the driver will make the device non-operational.

The device is actually released only after the refcnt of the hpriv
structure is 0, which means all its contexts were closed.

If we reset the device while a context is still open, there are
possibilities for unexpected behavior and crashes. For example, if the
process has a mapping of a register block that is now currently being
reset, and the process writes/reads to that block during the reset,
the device can get stuck.
