Now that there is a Barebox driver for the ADC, enable the clock to the TSC/ADC block. This machine doesn't use common clock framework clocks in Barebox, and instead enables any clock that might get used. Enalbing the clock could be made conditional based on enabling the driver, but none of the other clocks do this.
