Christian Gmeiner bc8e5fda78 drm/etnaviv: Restore some id values 
[ Upstream commit b735ee173f ]

The hwdb selection logic as a feature that allows it to mark some fields
as 'don't care'. If we match with such a field we memcpy(..)
the current etnaviv_chip_identity into ident.

This step can overwrite some id values read from the GPU with the
'don't care' value.

Fix this issue by restoring the affected values after the memcpy(..).

As this is crucial for user space to know when this feature works as
expected increment the minor version too.
