Revert "drm/etnaviv: Expose a few more chipspecs to userspace"

This reverts commit 1dccdba084897443d116508a8ed71e0ac8a031a4.

In userspace a different approach was choosen - hwdb. As a result, there
is no need for these values.

drm/etnaviv: Restore some id values

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.

drm/etnaviv: Expose a few more chipspecs to userspace

These ones will be needed to make use fo the NN and TP units in the NPUs
based on Vivante IP.

Also fix the number of NN cores in the VIPNano-qi.

drm/etnaviv: add hardware database

New versions of the Vivante kernel driver don't trust the hardware feature
bits anymore, but use an internal hardware database. This also includes
more feature fields than are available in hardware.

As we can't trust the hardware feature bits to be correct anymore, we need
to replicate the HWDB in etanviv. For now only the GC7000L as found on
the i.MX8M is supported.
