applesmc is very old, and all of its code is lumped into one driver. Fan control, sensors, the light sensor, the motion sensor and the keyboard backlight in a single file with its own way of talking to the SMC. It is hard to extend and to support new machines.

This series adds Intel Mac support to the macsmc drivers that were written for Apple Silicon (the Asahi implementation). The SMC works the same way on both platforms, so we share a lot of code with Asahi. Only the way of talking to the SMC differs.
