i2c: stm32f7: : use proper DMAENGINE API for terminationrenesas/terminate_sync
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.
