Patch Review

The core PMC register conversion. The `Architecture` type changes from `Try=
From<u8>` to `TryFrom<Bounded<u32, 6>>` and the `Revision` struct members c=
hange to `Bounded<u8, 4>`, with `.cast()` calls to convert between bounded =
types.

One inconsistency at line 829:
```rust
-            self.0,
+            self.inner,
```
The `Display` impl for `NV_PMC_BOOT_42` directly accesses `self.inner` to g=
et the raw value, while elsewhere the series consistently uses `self.into_r=
aw()` (e.g., line 819: `self.into_raw() >> Self::ARCHITECTURE_RANGE.start()=
`). Consider using `self.into_raw()` here too for consistency, or verify th=
at `self.inner` is the intended public API of the kernel register macro (it=
 may be =E2=80=94 the `inner` field might be `pub` on the generated struct).

The `From<Architecture> for Bounded<u32, 6>` implementation at lines 700-70=
3 maps each variant explicitly via `Bounded::<u32, _>::new::<0x16>()` etc.,=
 which is correct and avoids the previous `repr(u8)` cast.

The removal of `Default` from `Architecture` and `Revision` is good =E2=80=
=94 those defaults were artifacts of the old macro.
