PCI: designware: Use NULL instead of false

of_get_address() expects pointers in the third and fourth parameters.

Pass NULL in order to fix the following sparse warnings:

  drivers/pci/host/pcie-designware.c:433:51: warning: Using plain integer as NULL pointer
  drivers/pci/host/pcie-designware.c:433:58: warning: Using plain integer as NULL pointer
