Sam Bobroff 62d91dd285 drm/radeon: fix bad DMA from INTERRUPT_CNTL2 ...

The INTERRUPT_CNTL2 register expects a valid DMA address, but is
currently set with a GPU MC address.  This can cause problems on
systems that detect the resulting DMA read from an invalid address
(found on a Power8 guest).

Instead, use the DMA address of the dummy page because it will always
be safe.

Fixes: 25a857fbe9 ("drm/radeon/kms: add support for interrupts on SI")
