[ Upstream commit 19fb11d7220b8abc016aa254dc7e6d9f2d49b178 ]
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.
