Bryan O'Donoghue 9d6a8dab8d nvmem: imx-ocotp: Restrict OTP write to IMX6 processors 
i.MX7S/D have a different scheme for addressing the OTP registers inside
the OCOTP block. Currently it's possible to address the wrong OTP registers
given the disparity between IMX6 and IMX7 OTP addressing.

Since OTP programming is one-time destructive its important we restrict
this interface ASAP.
