In case the bus is in low power mode, the register writes (followed by a memory barrier) may take a long time (~4ms). This can cause the caller to block till the PCIe write is completed. Thus, even though PCI writes are posted, it can still block the caller. Hence, in case the bus is in low power mode (not in M0), or not in high throughput scenarios, queue the register write in a workqueue. The register write will happen in the delayed work context. In other cases, i.e ,when the bus is not in low power mode or in high thoughput scenarios, do the register writes in caller context.
