Andy Shevchenko ffe3f362de idma64: Don't try to serve interrupts when device is powered off 
[ Upstream commit 9140ce4787 ]

When iDMA 64-bit device is powered off, the IRQ status register
is all 1:s. This is never happen in real case and signalling that
the device is simply powered off. Don't try to serve interrupts
that are not ours.

Fixes: 667dfed986 ("dmaengine: add a driver for Intel integrated DMA 64-bit")
