[PATCH i-g-t 5/5] lib/igt_fb: Support fbs backed by local memory

[Thomas Hellström]

From: Ramalingam C <ramalingam.c at intel.com>

When local memory is supported, buffer object, backing the framebuffer
should be allocated from local memory.

Dumb buffer allocation takes care of this requirement from kernel
itself. So when we allocate BO through gem_create we make sure that
BO is from local memory.

v2:
  type is moved into i915 block [Januaz, Ashutosh]

v3: Update on gem_create_in_region() removal (Zbigniew)
