Hi,

The optional PRE_COPY state support for migration feature is introduced
by this series here[1](Thanks for that!). This is something HiSilicon
ACC driver can make use for early dev compatibility checks and have
made an attempt in the past here[2].

Adding this will speed up reporting the compatibility error early in
the migration process without the need to wait for complete data
transfer. This is sanity tested on a HiSilicon Platform.

Please take a look.

Regards,
Shameer
