serial: mxs-auart: Fix out-of-bounds access through serial port index
[ Upstream commit dd345a31bfdec350d2593e6de5964e55c7f19c76 ]
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.
