Subject: [PATCH RFC] usb: renesas_usbhs: fifo: : use proper DMAENGINE API for termination

dmaengine_terminate_all() is deprecated in favor of explicitly saying if
it should be sync or async. Here, we want dmaengine_terminate_sync()
because there is no other synchronization code in the driver to handle
an async case.

Shimoda-san, can you please double check if this works with the
additional locking in this function? Thank you!
