[PATCH 04/23] drm/i915/vm_bind: Support partially mapped vma resource

[Bhanuprakash Modem]

From: Niranjana Vishwanathapura <niranjana.vishwanathapura at intel.com>

As persistent vmas can be partialled mapped to an object,
remove restriction which require vma resource sg table to
be just pointer to object's sg table.
