drm/xe: Add sysfs entry to report per tile memory size
Add sysfs entry to read per tile physical memory
including stolen memory.
V5:
- rename var name and make it part of vram struct - Lucas
V4:
- %s/addr_range/physical_vram_size_byes, make it
user readable name - Joonas/Aravind
- Display in bytes - Joonas/Aravind
V3:
- Exclude DG1, replace sysfs_create_file/files - Aravind
V2:
- Use DEVICE_ATTR_RO - Aravind
- Dont put kobj on sysfs_file_create fail - Himal
- Skip addr_range sysfs create for non dgfx - Himal
