Subject: [PATCH] cpufreq: fix using cpufreq-dt as module

This driver can be built as a module since commit 3b062a086984 ("cpufreq:
dt-platdev: Support building as module"), but unfortunately this caused
a regression because the cputfreq-dt-platdev.ko module does not autoload.

Usually, this is solved by just using the MODULE_DEVICE_TABLE() macro to
export all the device IDs as module aliases. But this driver is special
due how matches with devices and decides what platform supports.

There are two of_device_id lists, an allow list that are for CPU devices
that always match and a deny list that's for devices that must not match.

The driver registers a cpufreq-dt platform device for all the CPU device
nodes that either are in the allow list or contain an operating-points-v2
property and are not in the deny list.

Enforce builtin compile of cpufreq-dt-platdev to make autoload work.
