[PATCH v2 03/19] gpu: nova-core: register: allow fields named `offset`

[Alexandre Courbot <acourbot@nvidia.com>]

`offset` is a common field name, yet using it triggers a build error due
to the conflict between the uppercased field constant (which becomes
`OFFSET` in this case) containing the bitrange of the field, and the
`OFFSET` constant constaining the offset of the register.

Fix this by adding `_RANGE` the field's range constant to avoid the
name collision.
