[SCSI] isci: export phy events via ->lldd_control_phy()
Allow the sas-transport-class to update events for local phys via a new
PHY_FUNC_GET_EVENTS command to ->lldd_control_phy(). Fixup drivers that
are not prepared for new enum phy_func values, and unify
->lldd_control_phy() error codes.
These are the SAS defined phy events that are reported in a
smp-report-phy-error-log command:
* /sys/class/sas_phy/<phyX>/invalid_dword_count
* /sys/class/sas_phy/<phyX>/running_disparity_error_count
* /sys/class/sas_phy/<phyX>/loss_of_dword_sync_count
* /sys/class/sas_phy/<phyX>/phy_reset_problem_count
