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-rockchip-host.c:553:2-9: line 553 is
  redundant because platform_get_irq() already prints an error

  drivers/pci/controller/pcie-rockchip-host.c:566:2-9: line 566 is
  redundant because platform_get_irq() already prints an error

  drivers/pci/controller/pcie-rockchip-host.c:576:2-9: line 576 is
  redundant because platform_get_irq() already prints an error
