[PATCH v3 2/2] radeon: use memcpy_to/fromio for UVD fw upload

I met a gpu addr bug recently and the kernel log tells me the pc is memcpy/memset and link register is radeon_uvd_resume. As we know, in some architectures, optimized memcpy/memset may not work well on device memory. Trival memcpy_toio/memset_io can fix this problem. BTW, amdgpu has already don
