There is no need to call the dev_err() function directly to print a
custom message when handling an error from either the platform_get_irq()
or platform_get_irq_byname() functions as both are going to display an
appropriate error message in case of a failure.

This change is as per suggestion from Coccinelle:

  drivers/pci/controller/pcie-xilinx-nwl.c:732:2-9: line 732 is
  redundant because platform_get_irq() already prints an error

  drivers/pci/controller/pcie-xilinx-nwl.c:589:2-9: line 589 is
  redundant because platform_get_irq() already prints an error

  drivers/pci/controller/pcie-xilinx-nwl.c:600:2-9: line 600 is
  redundant because platform_get_irq() already prints an error

  drivers/pci/controller/pcie-xilinx-nwl.c:801:2-9: line 801 is
  redundant because platform_get_irq() already prints an error
