77ed80c9ec misc: scu: Increase the timeout for MU communication
When power on some sources in Video system, current timeout 10ms is
too short and returns before SCU response. So increase the timeout
to 1s.

816d093c1a misc: imx8: scu: simplify code to make it extendable
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.

04b249656e imx8: scu: use dedicated MU for SPL
SPL runs in EL3 mode, except MU0_A, others are not powered on,
and could not be used. However normal U-Boot use MU1_A, so we
could not reuse the one in dts. And we could not replace the one
in dts with MU0_A, because MU0_A is reserved in secure world.

026381fc5a misc: imx8: scu: use platdata instead of priv data
priv data has not been allocated when doing bind, so it is
wrong to use dev_get_priv in bind call back.

Let's switch to use platdata in the driver to fix the issue.

8d773c4ab3 dm: core: Respect drivers with the DM_FLAG_PRE_RELOC flag in lists_bind_fdt()
Currently the comments of several APIs (eg: dm_init_and_scan()) say:

@pre_reloc_only: If true, bind only drivers with the DM_FLAG_PRE_RELOC
flag. If false bind all drivers.

The 'Pre-Relocation Support' chapter in doc/driver-model/README.txt
documents the same that both device tree properties and driver flag
are supported.

However the implementation only checks these special device tree
properties without checking the driver flag at all. This updates
lists_bind_fdt() to consider both scenarios.
