feature: Added changes for Porting Memory API with XE driver

Browse Source 
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.
