We should hold the reference returned by of_get_parent() and use it
to call of_node_put() for refcount balance.

Make it possible to build all clk drivers as modules, but default
remains built-in.
No functional changes.

During probe, bypass clocks (i.e. ee-in-xtal) are made from device-tree
inputs to provide input clocks which can be access through global name.
The cons of this method are the duplicated clocks, means more string
comparison.
Specify parent directly with device-tree clock name.
Remove the bypass clock registration from the ee probe function.

Like the PLL and MPLL, the controller may require some magic setting to
be applied on startup.
This is needed when the initial setting is not applied by the boot ROM.
The controller need to do it when the setting applies to several clock,
like all the MPLLs in the case of g12a.

The function used to probe the peripheral clock controller of the arm64
amlogic SoCs is mostly the same. We now have 3 of those controllers so
it is time to factorize things a bit.
