V4L/DVB (8499): zr36067: Rework device memory allocation
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.
