misc: mxc_ocotp: check fuse word before programming on i.MX7ULP On i.MX7ULP, the fuse words (except bank 0 and 1) only supports to write once, because they use ECC mode. Multiple writes may damage the ECC value and cause a wrong fuse value decoded when reading. This patch adds a checking before the fuse word programming, only can write when the word value is 0.
