In order to replace the fsl,scu txt file from bindings/arm/freescale,
we need to split it between the right subsystems. This patch documents
separately the 'watchdog' child node of the SCU main node.

In order to replace the fsl,scu txt file from bindings/arm/freescale,
we need to split it between the right subsystems. This patch adds the
fsl,scu.yaml in the firmware bindings folder. This one is only for
the main SCU node. The old txt file will be removed only after all
the child nodes have been properly switch to yaml.

-NXP i.MX System Controller Firmware (SCFW)
---------------------------------------------------------------------
-
-The System Controller Firmware (SCFW) is a low-level system function
-which runs on a dedicated Cortex-M core to provide power, clock, and
-resource management. It exists on some i.MX8 processors. e.g. i.MX8QM
-(QM, QP), and i.MX8QX (QXP, DX).
-
-The AP communicates with the SC using a multi-ported MU module found
-in the LSIO subsystem. The current definition of this MU module provides
-5 remote AP connections to the SC to support up to 5 execution environments
-(TZ, HV, standard Linux, etc.). The SC side of this MU module interfaces
-with the LSIO DSC IP bus. The SC firmware will communicate with this MU
-using the MSI bus.
-
-System Controller Device Node:
-============================================================
-
-The scu node with the following properties shall be under the /firmware/ node.
-
-Required properties:
--------------------
-- compatible: should be "fsl,imx-scu".
-- mbox-names: should include "tx0", "tx1", "tx2", "tx3",
- "rx0", "rx1", "rx2", "rx3";
- include "gip3" if want to support general MU interrupt.
-- mboxes: List of phandle of 4 MU channels for tx, 4 MU channels for
- rx, and 1 optional MU channel for general interrupt.
- All MU channels must be in the same MU instance.
- Cross instances are not allowed. The MU instance can only
- be one of LSIO MU0~M4 for imx8qxp and imx8qm. Users need
- to make sure use the one which is not conflict with other
- execution environments. e.g. ATF.
- Note:
- Channel 0 must be "tx0" or "rx0".
- Channel 1 must be "tx1" or "rx1".
- Channel 2 must be "tx2" or "rx2".
- Channel 3 must be "tx3" or "rx3".
- General interrupt rx channel must be "gip3".
- e.g.
- mboxes = <&lsio_mu1 0 0
- &lsio_mu1 0 1
- &lsio_mu1 0 2
- &lsio_mu1 0 3
- &lsio_mu1 1 0
- &lsio_mu1 1 1
- &lsio_mu1 1 2
- &lsio_mu1 1 3
- &lsio_mu1 3 3>;
- See Documentation/devicetree/bindings/mailbox/fsl,mu.yaml
- for detailed mailbox binding.
-
-Note: Each mu which supports general interrupt should have an alias correctly
-numbered in "aliases" node.
-e.g.
-aliases {
- mu1 = &lsio_mu1;
-};
-
-i.MX SCU Client Device Node:
-============================================================
-
-Client nodes are maintained as children of the relevant IMX-SCU device node.
-
-Example (imx8qxp):
--------------
-aliases {
- mu1 = &lsio_mu1;
-};
-
-lsio_mu1: mailbox@5d1c0000 {
- ...
- #mbox-cells = <2>;
-};

XTAL clocks are not exposed by SCU to OS via OS<->SCU communication protocol,
so remove unnecessary entries.

Both i.MX8QM and i.MX8DXL use the fallback fsl,scu-clk compatible.
They rely on the same driver generic part as the i.MX8QXP, so
lets add it to i.MX8QXP too, for consitency.

I'm preparing material for the next merge window, so just picked the
