Previously i915 was using a sysfs node to query the amount of local memory of a tile. For xe such sysfs node does not exist so the function was useless. Instead of a sysfs node, leverage the local memory size present in MemoryInfo (queried at init-stage) so that the output is now the same for both i915 and xe.
