ce2b3261b6 isci: unify constants
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.

TODO: remove SCI_MODE_SIZE infrastructure.
TODO: task.h is full of inlines that are too large

4b33981ade isci: unify phy data structures
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.

e1e72a00dd isci: Removed sci_base_object from scic_sds_phy.
The 'struct sci_base_object' was removed from the struct
scic_sds_phy and was replaced by a pointer to
struct isci_phy.

4393aa4e6b isci: fix fragile/conditional isci_host lookups
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

Adding support for PHY_FUNC_LINK_RESET and PHY_FUNC_DISABLE. This allow the
sysfs knob enable (both 0 and 1) and link_reset to work properly.
