[PATCH] docs/misra: replace R13.1 with R13.2

[Stefano Stabellini <sstabellini@xxxxxxxxxx>]

After looking closely at the R13.1 violations and potential fixes or
deviations, upon further reflection and discussions, we realized that it
is R13.2, limited to initializers list, that we want to comply with.
