OMAP: Improve register access in L3 Error handler.
* Changed the way of accessing L3 target registers from standard base rather than relative to STDERRLOG_MAIN. * Use ffs() to find error source from the L3_FLAGMUX_REGERRn register. * Remove extra l3_base[] entry. * Modified L3 custom error message.
