The current defconfig is inconsistent as it selects the mailbox and the clock for the hi6220 and the hi3660 without having their Kconfigs making sure the dependencies are correct. It ends up when selecting different versions for the kernel (for example when git bisecting) those options disappear and they don't get back, leading to unexpected behaviors. In our case, the cpufreq driver does no longer work because the clock fails to initialize due to the clock stub and the mailbox missing.
In order to have the dependencies correctly set when defaulting, let's do the same as commit 3a49afb84ca074e ("clk: enable hi655x common clk automatically") where we select automatically the driver when the parent driver is selected. With sensible defaults in place, we can leave other choices for EXPERT.
