[RESEND PATCH 1/4] omap: igep0020: name refactoring for future merge with IGEP3

Hi Mike,

The only comment I wanted to do is maybe I prefer rename the
board-igep0020 to board-igep00x0 to be more generic. Apart from this
these patch series looks good for me and has my ack. Thanks.

I suggest we do the rename separately later on. Otherwise it
easily gets classified as "crazy churn" type of patch, so best
to stick to just code coalescing and fixes for this merge window.

Tony
