usb: misc: onboard_usb_dev: skip suspend/resume sequence for USB5744 SMBus support

USB5744 SMBus initialization is done once in probe() and doing it in resume
is not supported so avoid going into suspend and reset the HUB.

There is a sysfs property 'always_powered_in_suspend' to implement this
feature but since default state should be set to a working configuration
so override this property value.

It fixes the suspend/resume testcase on Kria KR260 Robotics Starter Kit.
