arm: libpayload: Make cache invalidation take pointers instead of integers

This minor refactoring patch changes the signature of all limited cache
invalidation functions in coreboot and libpayload from unsigned long to
void * for the address argument, since that's really what you have in
95% of the cases and I think it's ugly to have casting boilerplate all
over the place.
