[PATCH v5 5/6] rust: cpufreq: Remove unnecessary `of` dependency in cpufreq example

[Igor Korotin]

Drop the explicit `use of` and `OF_ID_TABLE = None` assignment in the
cpufreq driver registration example.

Since `Adapter::OF_ID_TABLE` now defaults to `None`, drivers that do
not require OpenFirmware matching no longer need to import `of` or
define the constant explicitly.
