PCI: dra7xx: Propagate platform_get_irq() errors in dra7xx_pcie_probe()
platform_get_irq() returns an error code, but the pci-dra7xx driver ignores
it and always returns -EINVAL. This is not correct and prevents
-EPROBE_DEFER from being propagated properly.
Print and propagate the return value of platform_get_irq() on failure.
This issue was detected with the help of Coccinelle.
