usb: dwc3: handle usb2.0 gadget mode early hibernation event occurrence

commit  8a21f17ce0bba39d84e83ea7fdf5fad6cd6c633f from
https://github.com/Xilinx/linux-xlnx.git xlnx_rebase_v5.10

In USB 2.0, before connection done early hibernation interrupt
occurred. To avoid early Hibernation event for gadget mode set
DWC3_GCTL_GBLHIBERNATIONEN bit after connection done instead of
global core setup in dwc3 core.

Added host mode check in global core setup to avoid early bit
setting of DWC3_GCTL_GBLHIBERNATIONEN for gadget mode.
