This patch adds bindings for i.MX8qxp/qm Display Prefetch Resolve Gasket.

Reviewed-by: Rob Herring <robh@kernel.org>
Signed-off-by: Liu Ying <victor.liu@nxp.com>
---
Note that this depends on the 'two cell binding' clock patch set which has
already landed in Shawn's i.MX clk/imx git branch.  Otherwise, imx8-lpcg.h
won't be found.

v4->v5:
* No change.

v3->v4:
* Improve compatible property by using enum instead of oneOf+const. (Rob)
* Add Rob's R-b tag.

v2->v3:
* No change.

v1->v2:
* Use new dt binding way to add clocks in the example.

+description: |
+  The i.MX8qm/qxp Prefetch Resolve Gasket (PRG) is a gasket interface between
+  RTRAM controller and Display Controller.  The main function is to convert
+  the AXI interface to the RTRAM interface, which includes re-mapping the
+  ARADDR to a RTRAM address.

+  compatible:
+    enum:
