nvmem: imx-ocotp: handling clock
...
Before access ocotp nvmem area, the clock should be enabled.
Or, `hexdump nvmem` will hang the system. So, use such flow:
"
1. clock_enable_prepare
2. read nvmem ocotp area
3. clock_disable_unprepare
"

nvmem: imx-ocotp: Add i.MX6 OCOTP driver
...
This driver handles the i.MX On-Chip OTP Controller found in
i.MX6Q/D, i.MX6S/DL, i.MX6SL, and i.MX6SX SoCs. Currently it
just returns the values stored in the shadow registers.
