drm/nouveau/disp: fix cast removes address space of expression warnings
When build Linux kernel with 'make C=2', encounter the following warnings:
./drivers/gpu/drm/nouveau/dispnv50/disp.c:134:34: warning: cast removes address space '__iomem' of expression
./drivers/gpu/drm/nouveau/dispnv50/disp.c:197:34: warning: cast removes address space '__iomem' of expression
The data type of dmac->_push.mem.object.map.ptr is 'void __iomem *', but
converted to 'u32 *' directly and cause above warnings, now
recover their data types to fix these warnings.
