Stop using PRI*16 and %zu format specifiers (project-chip#17502)
* Stop using PRI*16 and %zu format specifiers Some libcs don't support them, use %u/%d/%x instead * Commit generated by running the following git-extras commands: git sed -f g '" PRIu16 "' 'u' git sed -f g '" PRIu16' 'u"' git sed -f g '" PRIx16 "' 'x' git sed -f g '" PRIx16' 'x"' git sed -f g '" PRIX16 "' 'X' git sed -f g '" PRIX16' 'X"' git sed -f g '" PRId16 "' 'd' git sed -f g '" PRId16' 'd"' git sed -f g '%zu' '%u' * Cast some %zu parameters due to warnings * Add lint rules * Run restyle Signed-off-by: Andrei Menzopol <andrei.menzopol@nxp.com> * Change c-style casts to c++-casts and restore variable type changes Signed-off-by: Andrei Menzopol <andrei.menzopol@nxp.com> * Add parentheses around static_cast arguments Signed-off-by: Andrei Menzopol <andrei.menzopol@nxp.com> * Run restyle locally Signed-off-by: Andrei Menzopol <andrei.menzopol@nxp.com>
