serial: ma35d1: Fix OF node reference leaks in console init

Browse source

ma35d1serial_console_init_port() stores matching UART device nodes in
ma35d1serial_uart_nodes[] with an extra of_node_get() so that console
setup can later read the "reg" property.  However, the stored references
are never released after console setup has finished using them.

Drop the stored node reference after ma35d1serial_console_setup() reads
the "reg" property, and clear the array slot to avoid leaving a stale
pointer behind.  Also release the iterator reference before breaking out
of for_each_matching_node(), since the normal iterator advance will not
run in that path.
