D0i3 adds additional interrupt reason bit, therefore we add a variable
intr_source to save the interrupt causes for further dispatching.
The interrupt cause is saved in the irq quick handler to achieve
unified behavior for both MSI enabled and shared interrupt platforms.

NM and SPS FW types that may run on ME device on server platforms
do not have valid MEI/HECI interface and driver should not
be bound to it as this might lead to system hung.
In practice not all BIOSes effectively hide such devices from the
OS and in some cases it is not possible.
We determine FW type by examining Host FW status registers in order to
unbind the driver.
In this patch we are adding check for ME on Cougar Point, Lynx Point
