When upstream ioctl helper is created it will try to create small
allocation, adding I915_GEM_CREATE_EXT_SET_PAT extension. If it
succeeds, for all resources with valid pat index value it will then
explicitly program pat index value with gem create ext call.
PrintBOCreateDestroyResult value can be used to:
- print whether the set pat extension is supported by the kernel, when
ioctl helper is created
- print whether set pat extension was added for a given gem create ext
call and what pat index value was programmed
Note: introduced changes are disabled by defualt.
Toggle DisableGemCreateExtSetPat can be used to enable new functionality.

The Memory Info object is used in the getState function for memory.
Some of the ULTS in the memory modules has been modified.
A function to return the sysfs nodes for the Memory address range has
been added in the IoctlHelper class corresponding to the XE and i915
driver.
