MX8 SoC is comprised of a few HW subsystems while some of them can be
reused in the different SoCs. So let's re-orginize them into subsystems
in device tree as well for the possible reuse of the common part.

Note, as there's still no devices of hsio subsys, so removed it
first instead of creating a subsys headfile with no devices.
They will be added back when new devices added.
