drm/msm/a5xx: fix context faults during ring switch
[ Upstream commit 32e7083429d46f29080626fe387ff90c086b1fbe ]
The rptr_addr is set in the preempt_init_ring(), which is called from
a5xx_gpu_init(). It uses shadowptr() to set the address, however the
shadow_iova is not yet initialized at that time. Move the rptr_addr
setting to the a5xx_preempt_hw_init() which is called after setting the
shadow_iova, getting the correct value for the address.
Fixes: 8907afb476ac ("drm/msm: Allow a5xx to mark the RPTR shadow as privileged")
