Geert Uytterhoeven 5f53807e75 serial: mxs-auart: Fix out-of-bounds access through serial port index
[ Upstream commit dd345a31bf ]

The auart_port[] array is indexed using a value derived from the
"serialN" alias in DT, or from platform data, which may lead to an
out-of-bounds access.

Fix this by adding a range check.
