MLK-13776 ocotp: Add fuse word checking before programming it 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.
