nvmem: imx-ocotp: Add support for banked OTP addressing

Browse source

The i.MX7S/D takes the bank address in the CTRLn.ADDR field and the data
value in one of the DATAx {0, 1, 2, 3} register fields. The current write
routine is based on writing the CTRLn.ADDR field and writing a single DATA
register only.

Fixes: 0642bac7da ("nvmem: imx-ocotp: add write support")
