Subject: [PATCH 4/4] clk: qcom: apcs-sdx55: Obtain clock from own OF node

So far we had to obtain all resources like clocks from the parent device,
because the qcom-sdx55-acps-clk platform device did not have an own OF node
assigned. Now that the parent mailbox driver assigns this, obtain the
resources directly from the assigned OF node to add support for describing
the clock controller in a separate child node. This allows breaking up
circular dependencies between the mailbox and the clock controller.

@Bjorn: If this looks good to you and you are fine with merging this
through the mailbox subsystem, could you provide an Acked-by here?
