An lldd need never look at the contents of an smp_discover_response frame.
Kill the remaining locations where isci is looking at it:

1/ covering for expanders that do not set the stp_attached bit (already
   handled by sas_ex_discover_end_dev)
2/ an overkill method to notifiy the rest of the driver about remote_device
   sas addresses

This is step 1 of removing the contortions to:
1/ unparse expander phy data into a smp discover frame
2/ open-code-parse the smp discover fram into a domain_device.dev_type equivalent

libsas has already spent cycles determining the dev_type, so now that
scic_sds_remote_device is unified with isci_remote_device we can
directly reference dev_type.

This might also change multi-level expander detection as we previously only
looked at dev_type == EDGE_DEV and we did not consider the FANOUT_DEV case.

Now that the core/lldd remote_device data structures are nominally unified
merge the corresponding sources into the top-level directory.  Also move the
remote_node_context infrastructure which has no analog at the lldd level.

Now that they are one in the same object remove the back pointer reference
in favor of container_of.

Removed any instances of the_* and this_* to variable names that are more
meaningful and tell us what they actually are.

At init and RNC resume we need to touch every phy in a port to be sure
we have initialized STP properties in the case where port_index !=
phy_index.  Also add some missing __iomem annotations.

c99 the struct initializers (scic_sds_remote_device_state_handler_table[]):
	1/ allows grep to consistently show method name associations.  The
	   naming is mostly consistent (except when it isn't) so this guarantees
	   coverage of present and future exception cases.
	2/ let's the compiler guarantee that the state table array entry
	   correlates with an actual state name and detect accidental reordering or
	   deletion of states.
	3/ allows default handler's to be identified easily

Support for the up to 2x4-port 6Gb/s SAS controllers embedded in the
chipset.

This is a snapshot of the first publicly available version of the driver,
commit 4c1db2d0 in the 'historical' branch.
