usb: gadget: fusb300_udc: bug fix of not doing idma reset for each time
Enter IDMA_RESET only when the controller has been reset or
the device has been plugged in to or out from a host. In
IDMA_RESET, we should disable the corresponding PRD interrupt.
Also there is a redundant space eliminated.
fusb300_udc driver is tested on FARADAY platform a369 with
FUSB300 FPGA v1.8
