Sam Bobroff 6fab6dbff4 drm/radeon: fix bad DMA from INTERRUPT_CNTL2 
[ Upstream commit 62d91dd285 ]

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: d8f60cfc93 ("drm/radeon/kms: Add support for interrupts on r6xx/r7xx chips (v3)")
Fixes: 25a857fbe9 ("drm/radeon/kms: add support for interrupts on SI")
Fixes: a59781bbe5 ("drm/radeon: add support for interrupts on CIK (v5)")
