isci: state machine cleanup
This cleans up several areas of the state machine mechanism: o Rename sci_base_state_machine_change_state to sci_change_state o Remove sci_base_state_machine_get_state function o Rename 'state_machine' struct member to 'sm' in client structs o Shorten the name of request states o Shorten state machine state names as follows: SCI_BASE_CONTROLLER_STATE_xxx to SCIC_xxx SCI_BASE_PHY_STATE_xxx to SCI_PHY_xxx SCIC_SDS_PHY_STARTING_SUBSTATE_xxx to SCI_PHY_SUB_xxx SCI_BASE_PORT_STATE_xxx to SCI_PORT_xxx and SCIC_SDS_PORT_READY_SUBSTATE_xxx to SCI_PORT_SUB_xxx SCI_BASE_REMOTE_DEVICE_STATE_xxx to SCI_DEV_xxx SCIC_SDS_STP_REMOTE_DEVICE_READY_SUBSTATE_xxx to SCI_STP_DEV_xxx SCIC_SDS_SMP_REMOTE_DEVICE_READY_SUBSTATE_xxx to SCI_SMP_DEV_xxx SCIC_SDS_REMOTE_NODE_CONTEXT_xxx_STATE to SCI_RNC_xxx Signed-off-by: Edmund Nadolski <edmund.nadolski@intel.com> Signed-off-by: Dave Jiang <dave.jiang@intel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
