ARM: imx6: report soc info via soc device
The patch enables soc bus infrastructure and adds a function
imx_soc_device_init() to report soc info via soc device interface for
imx6qdl and imx6sl. With the support, user space can get soc related
info by looking at sysfs like below.
$ cat /sys/devices/soc0/machine
Freescale i.MX6 Quad SABRE Smart Device Board
$ cat /sys/devices/soc0/family
Freescale i.MX
$ cat /sys/devices/soc0/soc_id
i.MX6Q
$ cat /sys/devices/soc0/revision
1.2
