From: Peng Fan <peng.fan at nxp.com>

Follow i.MX8, move the soc device register code to drivers/soc/imx
to simplify arch/arm/mach-imx/cpu.c

I planned to use similar logic as soc-imx8.c to restructure soc-imx.c
and merged the two files into one. But not sure, so still keep
the logic in cpu.c.

There is one change is the platform devices are not under
/sys/devices/soc0 after patch 1/4. Actually ARM64 platform
devices are not under /sys/devices/soc0, such as i.MX8/8M.
So it should not hurt to let the platform devices under platform dir.

Peng Fan (4):
  ARM: imx: use device_initcall for imx_soc_device_init
  ARM: imx: cpu: drop dead code
  ARM: imx: move cpu definitions into a header
  soc: imx: move cpu code to drivers/soc/imx
