[PATCH V2] soc: imx: Add i.MX8MN SoC driver support

[Anson . Huang]

From: Anson Huang <anson.hu...@nxp.com>

This patch adds i.MX8MN SoC driver support:

root@imx8mnevk:~# cat /sys/devices/soc0/family
Freescale i.MX

root@imx8mnevk:~# cat /sys/devices/soc0/machine
NXP i.MX8MNano DDR4 EVK board

root@imx8mnevk:~# cat /sys/devices/soc0/soc_id
i.MX8MN

root@imx8mnevk:~# cat /sys/devices/soc0/revision
1.0

Changes since V1:
        - i.MX8MN's anatop is fully compatible with i.MX8MM, so just use 
"fsl,imx8mm-anatop" as fallback
          compatible in i.MX8MN DT can avoid the machine check.
