[PATCH] Add more rules to docs/misra/rules.rst

[Stefano Stabellini <sstabellini@xxxxxxxxxx>]

From: Stefano Stabellini <stefano.stabellini@xxxxxxx>

As agreed during the last MISRA C discussion, I am adding the following
MISRA C rules: 7.1, 7.3, 18.3.

I am also adding 13.1 and 18.2 that were "agreed pending an analysis on
the amount of violations".

In the case of 13.1 there are zero violations reported by cppcheck.

In the case of 18.2, there are zero violations reported by cppcheck
after deviating the linker symbols, as discussed.
