dmaengine: pl330: Fix runtime PM support for terminated transfers
commit 5c9e6c2b2ba3ec3a442e2fb5b4286498f8b4dcb7 upstream.
PL330 DMA engine driver is leaking a runtime reference after any terminated
DMA transactions. This patch fixes this issue by tracking runtime PM state
of the device and making additional call to pm_runtime_put() in terminate_all
callback if needed.
Fixes: ae43b3289186 ("ARM: 8202/1: dmaengine: pl330: Add runtime Power Management support v12")
