[Intel-xe] [PATCH V2 0/3] drm/xe: Add sysfs entry for tile and relate it to GTs

[Tejas Upadhyay]

With the separation of xe_tile and xe_gt, We now consider
a PCI device (xe_device) to contain one or more tiles (struct xe_tile).
Each tile will contain one or two GTs (struct xe_gt).

Sysfs entries also needs to be aligned as follows:

drm/xe: Add sysfs entry per tile - Adds tile sysfs infrastructure
drm/xe: Add GTs under respective tile sysfs - Relates GTs to each tile
sysfs
drm/xe: Add sysfs entry to report per tile memory size - Reports actual
physical memory per respective tile

Sysfs entries will be as follows:
cat /sys/class/drm/card1/device/tileN/addr_range
