> sunxi_rsb_hw_init() issues a controller soft reset and waits for the reset
> bit to clear, but it ignores readl_poll_timeout()'s return value.
> 
> If the controller never leaves reset, probe can continue to publish child
> devices and system resume can report success without a usable RSB
> controller.
> 
> Return the timeout error, assert reset again, and disable the clock before
> leaving the hardware-init path.
