03e70a0271 drm/amdgpu: ih reroute for newer asics than vega20 
Starting Arcturus, it supports ih reroute through mmio directly
in bare metal environment. This is also valid for newer asics
such as Aldebaran.

9a9c59a8f4 drm/amdgpu: enable 48-bit IH timestamp counter 
By default this timestamp is 32 bit counter. It gets
overflowed in around 10 minutes.

b672cb1eee drm/amdgpu: enable retry fault wptr overflow 
If xnack is on, VM retry fault interrupt send to IH ring1, and ring1
will be full quickly. IH cannot receive other interrupts, this causes
deadlock if migrating buffer using sdma and waiting for sdma done while
handling retry fault.

Remove VMC from IH storm client, enable ring1 write pointer overflow,
then IH will drop retry fault interrupts and be able to receive other
interrupts while driver is handling retry fault.

IH ring1 write pointer doesn't writeback to memory by IH, and ring1
write pointer recorded by self-irq is not updated, so always read
the latest ring1 write pointer from register.

eed4bbd388 drm/amdgpu: correct IH_CHICKEN programming for aldebaran 
For aldebaran, psp firmware won't program IH_CHICKEN.
it now depends on driver to program it properly so
either bus address or gpu virtual address is just
working for ih ring.
