I'm not sure if it's a regression or not, but trying to upgrade from `svd2rust` 0.33 to 0.36, some register groups which were previously represented as an array are now explicitly listed.

Ie, from

```rs
pmux1_0: [Pmux1_; 16],
```

to

```rs
pmux1_0: Pmux1_0,
pmux1_1: Pmux1_1,
pmux1_2: Pmux1_2,
...
```

Is thus expected behaviour?
