Subject [PATCH kexec-tools 5/5] entry wants to be void *

The kexec info struct defines entry to be a void *, so pass around the
user supplied value as one.

This fixes the following warning:

gcc -g -O2 -fno-strict-aliasing -Wall -Wstrict-prototypes -I./include -I./util_lib/include -Iinclude/ -I./kexec/arch/ppc64/include  -c -MD -o kexec/kexec.o kexec/kexec.c
kexec/kexec.c: In function ‘my_load’:
kexec/kexec.c:773: warning: assignment makes pointer from integer without a cast
