dt-bindings: adc: axi-adc: add clocks property
Add a required clock property as we can't access the device registers if
the AXI bus clock is not properly enabled.
Note this clock is a very fundamental one that is typically enabled
pretty early during boot. Independently of that, we should really rely on
it to be enabled.
