Updates sandbox SCMI clock driver and tests since enabling CCF will mandate clock discovery that is all exposed SCMI clocks shall be discovered at initialization. For this reason, sandbox SCMI clock driver must emulate all clocks exposed by SCMI server, not only those effectively consumed by some other U-Boot devices. Therefore the sandbox SCMI test driver exposes 3 clocks (IDs 0, 1 and 2) and sandbox SCMI clock consumer driver gets 2 of them.
