etnaviv: hwdb: fix lookup of GC3000 in i.MX6QP

For whatever reason NXP decided to call the GC3000 in the i.MX6QP a
GC2000+. This being a lie is marked in the IP core by the upper half
of the revision register being all ones. The kernel driver already
fixes the model and revision when it encounters this core, but this
breaks matching in the HWDB, which uses the bogus model/rev from the
core.

Revert the fixup done by the kernel for the lookup in the HWDB.
