Fix DMA handling in radeon_dummy_page_init():
- Based on actual usage and on what Linux does, dummy_page.addr should
contain the physical bus address of the dummy page rather than its
virtual one. As a side-effect, correcting this bug fixes compilation
with PAE support enabled by getting rid of an inappropriate cast.
- Also based on actual usage of dummy_page.addr, theoretically Radeon
devices could do a maximum of 44-bit DMA. In reality, though, it is
more likely that they only support 32-bit DMA, at least that is what
radeon_gart_table_ram_alloc() sets up for, too. However, passing ~0
to drm_pci_alloc() as maxaddr parameter translates to 64-bit DMA on
amd64/64-bit machines. Thus, use BUS_SPACE_MAXSIZE_32BIT instead,
