Add binding for the Nordic nRF BICR memory. Signed-off-by: Gerard Marull-Paretas <[email protected]>
BICR (Board Information Configuration Registers) are located within the application UICR region (ref. MRAM mapping, table 38). Signed-off-by: Gerard Marull-Paretas <[email protected]>
The real, applicable and trusted values are the ones flashed into BICR. So, drop DT properties that replicate BICR and use runtime reads to BICR instead. Signed-off-by: Gerard Marull-Paretas <[email protected]>
Add a utility function to obtain LFOSC accuracy in PPM from BICR. Signed-off-by: Gerard Marull-Paretas <[email protected]>

DNM: will likely require reflashing BICR as some parameters were never written there. |

BICR should be taken as the source of truth for certain oscillator-related parameters, such as:
Currently, these were replicated in Devicetree, making it possible to have a non-fully functional system due to mismatches.
