[PATCH v2] misra: increase identifiers length to 63

[Stefano Stabellini <sstabellini@xxxxxxxxxx>]

Currently the identifiers characters limit is arbitrarily set to 40. It
causes a few violations as we have some identifiers longer than 40.

Increase the limit to another rather arbitrary limit of 63. Thanks to
this change, we remove a few violations, getting us one step closer to
marking Rules 5.2 and 5.4 as clean.

The ECLAIR configuration is already using 63, so this change matches
the rules.rst documentation with the ECLAIR behavior.

Signed-off-by: Stefano Stabellini <stefano.stabellini@xxxxxxx>

Changes in v2:
- use 63 instead of 64
- drop unneeded change to ECLAIR config
