[RFC PATCH v2 4/5] drm/amdgpu: make ring rptr_cpu_addr and wptr_cpu_addr typeless

[Runyu Xiao]

Now that all ring writeback slot accesses go through typed helper
wrappers, the stored CPU pointers no longer need to pretend that every
slot is a u32-based carrier.

Change rptr_cpu_addr and wptr_cpu_addr in struct amdgpu_ring from u32 *
to void *. The actual access width is now chosen at the call sites
through the typed 32-bit and 64-bit helpers, which better matches how
the writeback slots are used across different ring implementations.

This patch just removes the misleading static type from struct
amdgpu_ring after the call site conversions. No functional change is
intended.
