Many parts of the whole SW stack can program the ras enablement state
during the boot. Now we handle that case by adding one function which
check the ras flags and choose different code path.

add ras post init function.
Do some initialization after all IP have finished their late init.
Add new member flags which will control the ras work flow.
For now, vbios enable ras for us on boot. That might change in the
future.
So there should be a flag from vbios to tell us if ras is enabled or not
on boot. Looks like there is no such info now.
Other bits of the flags are reserved to control other parts of ras.

Currently, it is not clear how ras is supported. Both software and
hardware can set the supported. That is confusing.
Fix it by adding new member hw_supported.

It is a framework. Other IPs need call amdgpu_ras_xxx function instead of
psp_ras_xxx functions.
