feat(versal2): implement USB_SET_STATE dummy IOCTL

Browse source 
USB DWC3 driver calls firmware API to set USB D0/D3 power states.
In absence of firmware driver probe these PM APIs return -ENODEV
and DWC3 driver probe fails. Till PLM implement these PM APIs as
a temporary workaround add dummy PM implementation in TFA.
