igb: Make arrays on stack static const to avoid reallocation
While addressing the pin problem I noticed that all of the pin register
values where having to be pushed onto the stack each time the function was
called. To avoid that I am making them static const so that they should
only need to be allocated once and we can avoid all the instructions to get
them onto the stack..
