Directly manipulate the controller regsiter to suspend the usb bus
for HNP is not the proper way, this should be done through the usbcore

added for OTG devices interface driver if it's not enabled.

in ci_hdrc,
to make multiple OTG instances can exist in one system
- Change some otg fsm functions to be static
- Re-split timer init patch to avoid a later patch changing a previous one
in the same series
- Change timer structure memory allocation to be devm_kzalloc
- Update some format alignment and
a_idle if a_wait_vfall_tmout
