isci: remove base_controller abstraction

Merge struct sci_base_controller into scic_sds_controller, and also factor
the two types of state machine handlers into one function.  While we're at
it also remove lots of duplicate incorrect kerneldoc comments for the state
machine handlers.

- * sci_controller_get_memory_descriptor_list_handle() - This method simply

- * @controller: This parameter specifies the controller for which to retrieve

- * memory allocation utilities supporting alignment, then it is the
- * responsibility of the user to manually align the memory buffer for SCI.
- * Thus, the user may have to allocate a larger buffer to meet the alignment.
- * Additionally, the user will need to remember the actual memory allocation
- * addresses in order to ensure the memory can be properly freed when necessary
- * to do so. This method will return a valid handle, but the MDL may not be
- * accurate until after the user has invoked the associated
- * sci_controller_initialize() routine. A pointer to a physical memory
