str9xpec: Find flash controller from the chain.

Browse Source 
Find the flash controller by position since it is before the core,
not after it.

This fixes the problem that str9xpec enable_turbo (or any other
str9xpec command) did not work. (See my post in
http://forum.sparkfun.com/viewtopic.php?f=18&t=25542)
