[Intel-xe] [PATCH V5 0/4] 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 more 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/physical_vram_size_bytes

V5 :
   - Rename vram struct member size to usable size - Lucas
   - define ktype struct to const - Himal
V4 :
   - %s/addr_range/physical_vram_size_byes, make it
     user readable name - Joonas/Aravind
   - Display in bytes - Joonas/Aravind
   - Reorder headers and modify s/LMEM/VRAM - Matt/Aravind
V3 :
   - Make tile_sysfs_init return void and warn for errors
   - Exclude DG1 as it does not have TILE_ADDR_RANGE reg
   - Use sysfs_create_files -> sysfs_create_file
V2 :
   - Address review comments
