Description

### Description

Currently otp_ctrl only supports around 23 partitions. This is a limit that we are currently approaching.
#26746 exists to add a dedicated partition status register to allow for 32+ partitions.
From what I remember, the DV pass rate is about the same after applying this PR, but I believe the DV really needs to be reviewed (and adapted) by an expert.
@rswarbrick could you take a look at this?
