Add lsio mu alias for all lsio MUs that could communicate with SCU,
imx_scu_enable_general_irq_channel will parse the alias to get
the mu resource id, if using other MU, not MU1, the `mu_resource_id`
is not what we expect, so add alias to fix this issue.

The soc device register code will be moved to drivers/soc/imx/,
the code needs the cpu type definitions. So let's move the cpu
type definitions to a header.

This is preparation to move imx_soc_device_init to drivers/soc/imx/
There is no reason to must put dt devices under /sys/devices/soc0,
they could also be under /sys/devices/platform, so we could
pass NULL as parent when calling of_platform_default_populate.
Following soc-imx8.c
From: Peng Fan
Move the soc device register code to drivers/soc/imx to align with
i.MX8.
