We can use static mapping for TZIC to get rid of the
duplicated code for ioremap and the error handling of
ioremap, which will made code more clean and consistent.

v2: Remove the MX51_DEBUG related mapping which is conflict with TZIC.
    MX51_DEBUG related mapping is dead code, no-one use it.

I'd prefer to have that in two patches:

 - remove DEBUG mapping
 - add TZIC mapping

and in both cases adapt the listing in
arch/arm/plat-mxc/include/mach/hardware.h please.

Best regards
Uwe
