Introduce dedicated field 'power_on_delay_us' in onboard platform data and update its delay for USB5744 configuration. Hub itself requires some delay after reset to get to state where configuration data is going to be accepted. Without delay upcoming support for configuration via SMBUS is reporting a failure on the first SMBus write. i2c 2-002d: error -ENXIO: BYPASS_UDC_SUSPEND bit configuration failed Similar delay is likely also required for default configuration but because there is enough time (code execution) between reset and usage of the hub any issue is not visible but it doesn't mean delay shouldn't be reflected.
