[PATCH 2/2] powerpc/pseries: pci: Use NULL instead of 0 for pointers

[Tushar Behera <tushar.behera@linaro.org>]

The third argument for of_get_property() is a pointer, hence pass
NULL instead of 0.

Signed-off-by: Tushar Behera <tushar.behera@linaro.org>

This code is in a '#if 0' section, but I went ahead with the patch as
this is the only location in kernel where of_get_property is passed 0
as the third argument. If this function is not going to be used again,
then we may consider removing the code altogether.
