Add AST2700 clock controller driver and also use axiliary
device framework register the reset controller driver.
Due to clock and reset using the same register region.

Should this be moved into reset-aspeed.c?

If move to reset-aspeed.c that will have EXPORT_SYMBOL_GPL(aspeed_reset_controller_register);
And add one header ./drivers/reset/reset-aspeed.h. 
That is expected? Am I right?
