bus: sunxi-rsb: Split out controller init/exit functions

Browse source

This separates the resource acquisition from the hardware initialization
phase, so the hardware initialization can be repeated after system
suspend/resume. The same is done for the exit/remove function, except
that there is no resource deallocation phase due to the use of devres.

The requested RSB clock frequency is stored in `struct sunxi_rsb` so it
will be available when reinitializing the hardware.
