The current error paths for the cpuidle-psci driver, may leak memory or possibly leave CPU devices attached to their PM domains. These are quite harmless issues, but still deserves to be taken care of. Although, rather than fixing them by keeping track of allocations that needs to be freed, which tends to become a bit messy, let's convert into a platform driver. In this way, it gets easier to fix the memory leaks as we can rely on the devm_* functions. Moreover, converting to a platform driver also enables support for deferred probe, which subsequent changes takes benefit from. Signed-off-by:
