PCI: Remove dev_err() when handing an error from platform_get_irq()
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 suggestions from Coccinelle, e.g.,
drivers/pci/controller/dwc/pcie-armada8k.c:252:2-9: line 252 is
redundant because platform_get_irq() already prints an error
