Rather than requiring each board to explicitly disable the SPI controllers it is not using instead require boards to enable those that they are using. This is less work overall since normally at most one of the controllers is in use and avoids issues caused by inappropriate pinmuxing.

These symbols are only referenced in this source file so can be made static, and the efficiency table is constant data so can be declared as such. This avoids polluting the global namespace and fixes warnings from sparse.
The function arch_scale_freq_power() is still not prototyped or static, this is a separate issue as this is overriding a weak symbol from the scheduler which neglects to provide a prototype.

Ensure that unused I2C controllers are not activated, causing problems due to inappropriate pinmuxing or similar, by marking the controllers as disabled by default and requiring boards to explicitly enable those that are in use.
