Make scic_sds_port a member of isci_port and merge their lifetimes which
means removing the port table from scic_sds_controller in favor of the
one at the isci_host level. Merge ihost->sas_ports into ihost->ports.

that seemed not necessary and we can use existing information.

Removes unnecessary usage of BUG_ON macro, excluding core directory.
In some cases macro is unnecesary, check is done in caller function.
In other cases macro is replaced by if construction with

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
