i.MX6 defines OCOTP_CTRLn:ADDR as seven bit address-field with a one bit RSVD0 field, i.MX7 defines OCOTP_CTRLn:ADDR as a four bit address-field with a four bit RSVD0 field. i.MX8 defines the OCOTP_CTRLn:ADDR bit-field as a full range eight bits. i.MX6 and i.MX7 should return zero for their respective RSVD0 bits and ignore a write-back of zero where i.MX8 will make use of the full range. This patch expands the bit-field definition for all users to eight bits, which is safe due to RSVD0 being a no-op for the i.MX6 and i.MX7.
