Prepare the introduction of PX30 support by using
drm_encoder_helper_funcs as platform data instead of multiple register
names which are specific to rk3288 and not generic to all Rockchip
IPs. This way adding support for a new flavor of a similar IP will be
a matter of adding the relevant helper funcs.

Callback unbinding needs to be done after nf_flow_table_free(),
otherwise entries are not removed from the hardware.
Update nft_unregister_flowtable_net_hooks() to call
nf_unregister_net_hook() instead since the commit/abort paths do not
deal with the callback unbinding anymore.
Add a comment to nft_flowtable_event() to clarify that
flow_offload_netdev_event() already removes the entries before the
callback unbinding.

Sometimes clk drivers are attached to devices which are children of a
parent device that is connected to a node in DT. This happens when
devices are MFD-ish and the parent device driver mostly registers child
devices to match against drivers placed in their respective subsystem
directories like drivers/clk, drivers/regulator, etc. When the clk
driver calls clk_register() with a device pointer, that struct device
pointer won't have a device_node associated with it because it was
created purely in software as a way to partition logic to a subsystem.
This causes problems for the way we find parent clks for the clks
registered by these child devices because we look at the registering
device's device_node pointer to lookup 'clocks' and 'clock-names'
properties. Let's use the parent device's device_node pointer if the
registering device doesn't have a device_node but the parent does. This
simplifies clk registration code by avoiding the need to assign some
device_node to the device registering the clk.
