powerpc/scom: Return NULL instead of 0
Function scom_map_device() returns data type 'scom_map_t', which is a
typedef for 'void *'. This functions is currently returning NULL and zero,
which causes the following warning by 'sparse':
arch/powerpc/sysdev/scom.c:63:24: warning: Using plain integer as NULL pointer
arch/powerpc/sysdev/scom.c:86:24: warning: Using plain integer as NULL pointer
This patch simply replaces zero by NULL.
