i2c/isp1301_omap: Build fixes, whitespace
Build fixes for isp1301_omap driver. I think an earlier version of this must have gotten lost somewhere, or maybe it only went into the Linux-OMAP tree. Also, some whitespace fixes to bring this more into sync with the version of this found in the Linux-OMAP tree. (That version has updates for the OTG controller on the OMAP 1710 which break that functionality on OMAP 161x boards like the H2, so merging all of it is not currently an option.)
