Bug#1050587: linux: cpufreq-dt requires manually loading cpufreq-dt-platdev (6.5 regression)

[Lukas F. Hartmann]

I encountered the same issue on MNT Reform with Banana Pi CM4 module
(Amlogic A311D / meson g12b). The processor operates at lowest speed and
toolig can't display CPU freqs, until the cpufreq-dt-platdev module is
loaded manually.
