early_init_dt_scan() accepts "void *", so c6x needs to type cast 'fdt'
to "void *" to avoid warning:

CC arch/c6x/kernel/setup.o
arch/c6x/kernel/setup.c: In function 'machine_init':
arch/c6x/kernel/setup.c:290:21: warning: passing argument 1 of 'early_init_dt_scan' discards 'const' qualifier from pointer target type [-Wdiscarded-qualifiers]
early_init_dt_scan(fdt);
^
In file included from arch/c6x/kernel/setup.c:19:0:
include/linux/of_fdt.h:75:13: note: expected 'void *' but argument is of type 'const void *'
extern bool early_init_dt_scan(void *params);
^
