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:
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.
/ allows default handler's to be identified easily

This will be replaced by state machine tracepoints and should have been a part
of the logger removal.
Ran across scic_sds_port_decrement_request_count() which is an ugly macro
which silently hides accounting errors. Turn it into a WARN_ONCE to see if it
ever triggers.
