* OMAP1 platform GPIO was not working correctly on omap850 due to missing OMAP850
method checks. This is now correctly implemented and working.
* A #if statement in common.c was excluding code for omap730 and 15xx, and should
have also been excluding the code for omap850. This is now fixed.
* omap850 mux was being done differently/incorrectly for omap850. This is now fixed.
* INT_IH2_IRQ was not being defined for omap850, causing interrupts to not work
on omap850. This is now fixed.
