dmaengine: Revert "dmaengine: pl330: issue_pending waits until WFP state"

[ Upstream commit afc89870ea677bd5a44516eb981f7a259b74280c ]

This reverts commit 22a9d9585812 ("dmaengine: pl330: issue_pending waits
until WFP state") as it seems to cause regression in pl330 driver.
Note the issue now exists in mainline so a fix to be done.
