Subject: [PATCH 0/9] Add SoC serial number support for i.MX6/7 SoCs

i.MX6/7 SoCs have 64-bit unique ID stored in OCOTP bank 0, word 1/2,
read them out as SoC serial number which can be used from userspace:

root@...7dsabresd:~# cat /sys/devices/soc0/serial_number
0000028FF618B953

Add support for i.MX6Q/6DL/6SL/6SX/6SLL/6UL/6ULL/6ULZ/7D, as they have
same unique ID layout in OCOTP.
