mb/google/brya/var/redrix: Add ACPI fan definitions
Add entries in overridetree.cb required for exposing fan control via ACPI, which is used then by acpi-fan driver in Linux kernel. This includes: 1. Fan duty-cycle/rpm table. The RPM numbers were adjusted to the values reported by ACPI on different duty cycle levels. 2. Dummy Active DPTF policy. This is required to mark the TFNx devices as active and therefore let the acpi-fan driver probe.
