It may change wakeup flag, and cause port change detect(PCD) enable setting change. - For ID wakeup, it should not call host's fsl_usb_recover_hcd at ID interrupt. The coming ID switch event will resume host. - Do not need enable wakeup interrupt for host at platform driver resume routine, it may introduce unnessary wakeup interrupt during bus resume. The wakeup will be enabled again when usb host goes to controller again due to autosuspend. - When there is no gadget enabled, the otg port is still at host mode with interrupt enabled, so when male Micro-B to female A-type cable with usb device plugs in, there will be PCD interrupt before hcd core leaves suspend mode.

The reason why it creates bugs that it changes (auto)suspend/resume

This issue will happen only when suspend bit is set but phcd is not set
The root cause of this issue is the IC defect.
    - If the suspend bit is set without phcd bit set, host controller
      can't resume normally
    - The workaround is after set suspend bit, we need set the following
      bit in USB PHY at once:
      HW_USBPHY_PWD_RXPWDRX
      HW_USBPHY_PWD_RXPWDDIFF
      HW_USBPHY_PWD_RXPWD1PT1
