drm/amdgpu: Fix shift type in amdgpu_debugfs_sdma_sched_mask_set()
The "mask" and "val" variables are type u64. The problem is that the
BIT() macros are type unsigned long which is just 32 bits on 32bit
systems.
It's unlikely that people will be using this driver on 32bit kernels
and even if they did we only use the lower AMDGPU_MAX_SDMA_INSTANCES (16)
bits. So this bug does not affect anything in real life.
Still, for correctness sake, u64 bit masks should use BIT_ULL().
