v11 changes:
- Dropping the use of cxl_memdev_state and going back to using
cxl_dev_state.
- Using a helper for an accel driver to allocate its own cxl-related
struct embedding cxl_dev_state.
- Exporting the required structs in include/cxl/cxl.h for an accel
driver being able to know the cxl_dev_state size required in the
previously mentioned helper for allocation.
- Avoid using any struct for dpa initialization by the accel driver
adding a specific function for creating dpa partitions by accel
drivers without a mailbox.
