Subject: [PATCH V3 11/21] PCI: tegra194: Remove IRQF_ONESHOT flag during Endpoint interrupt registration

Tegra PCIe endpoint has a common interrupt that notifies hardware events
like link up, LTR send, etc. DMA completion event is also notified over
this interrupt. Remove IRQF_ONESHOT flag from interrupt registration and
allow DMA driver to share this interrupt.
