gpu/radeon: Set flag to indicate broken 64-bit MSI
Some radeon ASICs don't support all 64 address bits of MSIs despite advertising support for 64-bit MSIs in their configuration space. This breaks on systems such as IBM POWER7/8, where 64-bit MSIs can be assigned with some of the high address bits set. This makes use of the newly introduced "no_64bit_msi" flag in structure pci_dev to allow the MSI allocation code to fallback to 32-bit MSIs on those adapters.

Patch to the driver is identical to the reviewed one, I dropped the arch/powerpc hunk rewrote the subject and cset comment.
