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.)
