Description
### Description
Recommend to make pin strength and slew rate configurable at `ROM` and `ROM_EXT` level:
* Allocate OTP words to store the pin configuration for interfaces used in the ROM (e.g. `SPI_DEV`)
* Support pin default settings in ownership config and/or based on `SW_STRAP` settings.
Contributor guide
Research direction
Start by tracing the ROM and ROM_EXT entry points that configure interfaces such as SPI_DEV, then review how OTP words, ownership config, and SW_STRAP settings are represented. Done means defining and implementing a clear way for ROM-stage pin strength and slew rate defaults to be configured through the proposed sources.
