[U-Boot] wrong macro name for at91-ssc

Hi, everybody

I found the macro name for at91-ssc base may be wrong, in arch-at91/at91rm9200.h has he flowwing define:

#define AT91_SCC_BASE 0xFFFD0000 /* 4x 0x4000 Offset */

May be it should be :

#define AT91_SSC_BASE 0xFFFD0000 /* 4x 0x4000 Offset */

And I search all header files in arch/arm dir, Can't found any definition for ssc registers, why? Nobody use this pheri !?
