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.
