[COMMON] dma: Remove FLUSHP for dev2mem transfer

In Dev2mem transfer, peripheral de-asserts the PERIPHERAL_REQUEST
on the very next clock edge of its finished request because
data transfer is already completed on the peripheral side.

In this case, micro code does not have to do FLUSHP
because there should not be any synchronization issues.
