The power domain tree is not accepted by Linux Kernel upstream.
only a single pd node is used currently, as following:
pd: imx8qx-pd {
compatible = "fsl,imx8qm-scu-pd", "fsl,scu-pd";
#power-domain-cells = <1>;
};
So to migrate to use upstream linux dts, we also need a driver
to support this.
This patch is to support the new method, compared with legacy power
domain tree, it will be simpiler, because each device will
has resource id as power domain index, it will be directly passed
to scfw, and no need to let power domain build that tree. If multiple
power domain is needed, it is the dts node should has correctly power
domains entry added and sequence correct.

The current i.MX8 power domain driver is based on i.MX vendor
power domain tree which will retire later.
The Linux upstream use a single pd node for power domain driver,
and U-Boot will adopt that. When U-Boot i.MX8 dts synced with
Linux Kernel upstream and related driver ready, the legacy
driver will be removed.

clk and pinctrl will be get(probed) during each device probe,
we don't need to probe them in scu driver. Only need to bind the sub-nodes
(clk and iomuxc) of MU node with their drivers.
So drop the code to probe the clk/pinctrl, and this patch will make it
easy to add more subnodes.

The Linux imx2_wdt driver uses a fsl,ext-reset-output boolean in the
device tree to specify whether the board design should use the external
reset instead of the internal reset. Use this boolean to determine which
mode to use rather than using external reset unconditionally.
For the legacy non-DM mode, the external reset is always used in order
to maintain the previous behavior.
