This cannot be fixed nicely as the OpenTitan I2C does not allow direct polling of NAKs, only awkwardly through the absence of an interrupt...

TODO:

Patch OpenTitan I2C to properly expose NAK events on pollable device register.
Fix write HAL functions to use this register to wait for end of write cycle.
