drm/i915/dsb: DSB context creation.
This patch adds a function, which will internally get the gem buffer
for DSB engine. The GEM buffer is from global GTT, and is mapped into
CPU domain, contains the data + opcode to be feed to DSB engine.
v1: Initial version.
v2:
- removed some unwanted code. (Chris)
- Used i915_gem_object_create_internal instead of _shmem. (Chris)
- cmd_buf_tail removed and can be derived through vma object. (Chris)
v3: vma realeased if i915_gem_object_pin_map() failed. (Shashank)
v4: for simplification and based on current usage added single dsb
object in intel_crtc. (Shashank)
v5: seting NULL to cmd_buf moved outside of mutex in dsb-put(). (Shashank)
v6:
- refcount machanism added.
- Used atomic_add_return and atomic_dec_and_test instead of
atomic_inc and atomic_dec. (Jani)
