board/kup/common/pcmcia.c: Fix GCC 4.6 compiler warnings

Fix:
../common/pcmcia.c: In function 'pcmcia_hardware_enable':
../common/pcmcia.c:23:20: warning: variable 'immap' set but not used
[-Wunused-but-set-variable]
../common/pcmcia.c: In function 'pcmcia_voltage_set':
../common/pcmcia.c:152:20: warning: variable 'immap' set but not used
[-Wunused-but-set-variable]
