Merged states and substates into one state machine, as we always
unconditionally transitioned to the substate machine it was straightforward to
enter that substate from the starting state.

cross driver constants are spread out over multiple header files, consolidate
them into isci.h, and push some includes out to the source files that need
them.

Make scic_sds_phy a member of isci_phy and merge their lifetimes which
means removing the phy table from scic_sds_controller in favor of the
one at that isci_host level.

The 'struct sci_base_object' was removed from the struct
scic_sds_phy and was replaced by a pointer to
struct isci_phy.

A domain_device can always reference back to ->lldd_ha unlike local lldd
structures. Fix up cases where the driver uses local objects to look up the
isci_host. This also changes the calling conventions of some routines to
expect a valid isci_host parameter rather than re-lookup the pointer on entry.
Incidentally cleans up some macros that are longer to type than the open-coded
equivalent:
isci_host_from_sas_ha
isci_dev_from_domain_dev
