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
