serial: imx: Fix out-of-bounds access through serial port index
[ Upstream commit 5673444821406dda5fc25e4b52aca419f8065a19 ]
The imx_ports[] 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.
Fixes: ff05967a07225ab6 ("serial/imx: add of_alias_get_id() reference back")
