[PATCH v2 13/19] gpu: nova-core: register: split @io rule into fixed and relative versions

[Alexandre Courbot]

We used the same @io rule with different patterns to define both the
fixed and relative I/O accessors. This can be confusing as the matching
rules are very similar.

Since all call sites know which version they want to call, split @io
into @io_fixed and @io_relative to remove any ambiguity.
