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

From: Anson Huang <Anson.Huang@....com>

This patch adds i.MX8MN SoC driver support:

root@...8mnevk:~# cat /sys/devices/soc0/family
Freescale i.MX

root@...8mnevk:~# cat /sys/devices/soc0/machine
NXP i.MX8MNano DDR4 EVK board

root@...8mnevk:~# cat /sys/devices/soc0/soc_id
i.MX8MN

root@...8mnevk:~# cat /sys/devices/soc0/revision
1.0

Signed-off-by: Anson Huang <Anson.Huang@....com>

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.
