vc04_services contains a debug logging mechanism. The log is
maintained in a shared memory area between the kernel and the
firmware. Changing the sizes of the data in this area would
require a firmware change which is distributed independently
from the kernel binary.
One of the items logged is the address of received messages.
This address is a pointer, but the debugging slot used to store
the information is a 32 bit integer.
Luckily, this value is never interpreted by anything other
then debug tools and it is expected that a human debugging
the kernel interpret it.
This change adds a cast to long before the original cast
to int to silence the warning.
