[PATCH V2 0/2] Add gpu_buddy_allocated_addr_to_block helper and its Kunit tests

[Tejas Upadhyay <tejas.upadhyay@intel.com>]

Add helper with primary purpose is to efficiently trace a specific
memory address back to its corresponding TTM buffer object.

Also Add KUnit tests for testing it.

v2
- Drop the mutex and lockdep annotation; standalone KUnit tests do not
  register a driver lock.
