From: Keerthy <j-keerthy@xxxxxx>
Currently devm_request_irq is being called before base, pci fields
of dra7xx_pcie structure are populated. It is called even before
pm_runtime_enable and pm_runtime_get_sync are called. This will
lead to exceptions if in case an interrupt is triggered before
the all of the above are done. Hence push the devm_request_irq
call to the end of the probe.
