We update 'extra-y' based on CONFIG_OF_ALL_DTBS three times. It would be
far more straight forward if we rather update dtb-y to include all .dtb
files if CONFIG_OF_ALL_DTBS is enabled.

V6->V7:
- Dropped the first 4 patches, already merged.
- Patch 1/3 is new, suggested by Rob and slightly modified by me.
- Adapt Patch 3/3 to the new rule and name the overlay dtbs as .dtbo.

the callbacks is improved, so different
parts looking to provide their callbacks don't need to think about

Rename freq_scale to a less generic name, as it will get exported soon
for modules. Since x86 already names its own implementation of this as
arch_freq_scale, lets stick to that.
