hwrng: drivers - Drop unused assignment to pci driver_data

Explicitly assigning 0 to driver_data in drivers not using this member
has no benefit. Drop these and similarly depend on the compiler to
zero-initialize the list terminator.

This is a preparation for making struct pci_device_id::driver_data an
anonymous union (which makes initializing using a list expression fail),
but it's also a nice cleanup by itself.

It was verified on x86 and arm64 that this change doesn't introduce
changes to the compiled drivers.
