[PATCH 4/4] arm64: dts: qcom: qcs6490-rb3gen2: add the clock controller

[Alex Elder]

The clock (and reset) controller within the TC9564 SoC is accessed
via a PCI endpoint bus through BAR 4 of the first embedded PCIe
function.  A syscon node is created to provide access to a range
of memory that is used by the clock/reset controller and shared
by other devices.
