We no longer need to maintain some of the GuC ABI definitions
inside the i915 driver as the shared one are exactly the same.

- *
- * Current status of the each buffer is stored in the buffer descriptor.
- * Buffer descriptor holds tail and head fields that represents active data
- * stream. The tail field is updated by the data producer (sender), and head
- * field is updated by the data consumer (receiver)::

- * For Gen9+, there are 16 software scratch registers 0xC180-0xC1B8,

- * itself uses an 4-element array to store the H2G message.
- *
- * For Gen11+, there are additional 4 registers 0x190240-0x19024C, which
- * are, regardless on lower count, preferred over legacy ones.

- * The MMIO based communication is mainly used during driver initialization
- * phase to setup the `CTB based communication`_ that will be used afterwards.
