[PATCH v2 06/19] gpu: nova-core: register: remove `try_` accessors for relative registers

[Alexandre Courbot <acourbot@nvidia.com>]

Relative registers are always accessed using a literal base, meaning
their validity can always be checked at compile-time. Thus remove the
`try_` accessors that have no purpose.
