Subject: [PATCH 7/8] arm64: imx8qxp:dtsi: Introduce DC0 subsystem
This patch adds basic i.MX8qxp DC0 subsystem support, which includes
the irqsteer, LPCG clock controller, Display Processing Unit(DPU) and
it's prefetch engines - Prefetch Resolve Gaskets(PRG) and Display Prefetch
Resolve Channels(DPRC).
Note that the clocks are still referenced in the legacy way instead of
the new "two cells" binding way. So, prone to update as soon as the SoC
device tree is converted to follow the new way.
