John Hubbard 487f9b3dc6 rust: cpufreq: suppress clippy::double_parens in Policy doctest ...

The kernel fmt! proc macro wraps each format argument as &(arg). Passing a
tuple such as (a, b) produces &((a, b)) after expansion. Clippy flags that
as double_parens, but it is a false positive fixed in Clippy 1.92 [1] [2].

Suppress the warning on the affected doctest function with a reason
attribute so it can be removed once the minimum toolchain moves past 1.92.

[ We may end up deciding to support per-version Clippy lints, in which
  case we will need [3].

  In the future, if [4] gets fixed, we may be able to use
  `Delimiter::None` as Gary suggested in [5].
