initrd: cast `initrd_start' to `void *'
commit fb6624ebd912e3d6907ca6490248e73368223da9 (initrd: Fix virtual/physical
mix-up in overwrite test) introduced the compiler warning below on mips,
as its virt_to_page() doesn't cast the passed address to unsigned long
internally, unlike on most other architectures:
init/main.c: In function `start_kernel':
init/main.c:633: warning: passing argument 1 of `virt_to_phys' makes pointer from integer without a cast
init/main.c:636: warning: passing argument 1 of `virt_to_phys' makes pointer from integer without a cast
For now, kill the warning by explicitly casting initrd_start to `void *', as
that's the type it should really be.
