Presently the root node is initialized by way of kzalloc on the parent
data structure, which by chance happens to do the bulk of what an
explicit initialization does with GFP_NOWAIT semantics. This however is
more by luck than by design, and as we ideally want to permit radix node
allocations access to the emergency pools anyways, add in the proper
initializer with the desired mask.

The disabling of the init op for non-legacy clocks neglected to do the
same in the core clock framework, resulting in a build failure. Fix it
up.

Now that clk_set_rate_ex() is gone, there is also no way to get at rate
setting algo id, which is now also completely unused. Kill it off before
new clock ops start using it.

With the refactoring of the SH7722 clock framework some time ago this
abstraction has become unecessary. Kill it off before anyone else gets
the bright idea to start using it.

The radix tree retry logic got a bit of an overhaul and subsequently
broke the virtual IRQ subgroup build. Simply switch over to
radix_tree_deref_retry() as per the filemap changes, which the virq
lookup logic was modelled after in the first place.

The clk_round_parent() change introduced various checkpatch warnings,
tidy them up.
