Their frequency is set by the bitstream, so having them located in -fabric.dtsi is not a problem - they're just as "fixed" as the IP blocks etc used in the FPGA fabric. However, their configuration can be read at runtime (and to an extent they can be controlled, although the intended usage is static configurations set by the bitstream) through the system controller bus. In the v2209 reference design a single CCC (north-west corner) is enabled, using a 50 MHz off-chip oscillator as its reference. Updating to the v2209 reference design is required.
