In certain types of chips, such as VEGA20, reading the amdgpu_regs_smc file could result in an abnormal null pointer access when the smc_rreg pointer is NULL. Below are the steps to reproduce this issue and the corresponding exception log:

1. Navigate to the directory: /sys/kernel/debug/dri/0
2. Execute command: cat amdgpu_regs_smc
3. Exception Log::

When DML 2 was introduced, it changed part of the generic sequence of
DC, which caused issues on previous DCNs with DMUB support. This commit
ensures the new sequence only works for new DCNs from 3.5 and above.

When DML2 was introduced, it targeted only new DCN versions. For
controlling which ASIC should use this new version of DML, it was
introduced the using_dml2 attribute. To avoid ambiguities, this commit
explicitly sets using_dml2 to false in all ASICs that do not support
DML2.
