It seems to be usual for MFD devices that the created 'clock sub-device'
do not have own DT node. The clock provider information is usually in the
main device node which is owned by the MFD device. Change the devm variant
of clk of-provider registration to check the parent device node if given
device has no own node or if the node does not contain the #clock-cells
property. In such case use the parent node if it contains the #clock-cells.

Add support for the lpass clock controller found on SDM845 based devices.
This would allow lpass peripheral loader drivers to control the clocks to
bring the subsystem out of reset.
LPASS clocks present on the global clock controller would be registered
with the clock framework based on the protected-clock flag. Also do not
gate these clocks if they are left unused, as the lpass clocks require
the global clock controller lpass clocks to be enabled before they are
accessed. Mark the GCC lpass clocks as CRITICAL, for the LPASS clock
access.

The #reset-cells was listed as optional in the bindings for
qcom,sdm845-videocc.  There's no reason for it to be optional.  As per
Stephen [1]:

> We should update the binding to make it a required property. It
> doesn't make any sense why that property would be optional given
> that the hardware either has support for resets or it doesn't.

sdm845 support is still in its infancy so we shouldn't be affecting
any real device trees by modifying the bindings here.

In the bindings that landed for the gpucc we require that the XO clock
(one possible parent of the gpucc) be listed.  The code doesn't use
this yet--this is just to allow us to move toward the day when it does
use it.  What the code does do today is to hardcode the parent name to
"bi_tcxo".  That's all well and good.

...but the example in the bindings shows this clock mapping to the
clock "xo_board".  On the current sdm845.dtsi file the "xo_board"
clock is a fixed clock with an output name of "xo_board".  The clock
with the name "bi_tcxo" is actually provided by the RPMh Clock
Controller.  Presumably that's the one that was wanted.

Let's update the example to make this clearer.
