From: Niranjana Vishwanathapura <niranjana.vishwanathapura at intel.com>
Add basic tests for VM_BIND functionality. Bind the buffer objects in
device page table with VM_BIND calls and have GPU copy the data from a
source buffer object to destination buffer object.
Test for different buffer sizes, buffer object placement and with
multiple contexts.
v2: Add basic test to fast-feedback.testlist
v3: Run all tests for different memory types,
pass VA instead of an array for batch_address
v4: Iterate for memory region types instead of hardcoding,
use i915_vm_bind library functions
v5: Validate synchronous vm_bind, require blt engine,
use mr->gtt_alignment instead of HAS_64K_PAGES,
change info to debug messages, remove igt_collection usage,
fix dg2 alignment issue
v6: Port as per uapi reserved field changes
v7: Use syncobj library functions, rebase
