Allocate zoran devices dynamically. Currently, the zr36067 driver stores the device structures in a global array, with room for 4 devices. This makes the bss section very large (90 kB!), and given that most users, I suspect, have only one zoran device, this is a waste of kernel memory. Allocating the memory dynamically lets us use only the amount of memory we need.
