isci: phy state machine cleanup step1

 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
