hw/char/max78000_uart: Destroy FIFO on deinit
In the max78000_uart we create a FIFO in the instance_init function,
but we don't destroy it on deinit, so ASAN reports a leak in the
device-introspect-test:
#0 0x561cc92d5de3 in malloc (/mnt/nvmedisk/linaro/qemu-from-laptop/qemu/build/arm-asan/qemu-system-arm+0x21f1de3) (BuildId: 98fdf9fc85c3beaeca8eda0be8412f1e11b9c6ad)
#1 0x70cbf2afab09 in g_malloc (/lib/x86_64-linux-gnu/libglib-2.0.so.0+0x62b09) (BuildId: 1eb6131419edb83b2178b682829a6913cf682d75)
#2 0x561ccc4c884d in fifo8_create /mnt/nvmedisk/linaro/qemu-from-laptop/qemu/build/arm-asan/../../util/fifo8.c:27:18
#3 0x561cc9744ec9 in max78000_uart_init /mnt/nvmedisk/linaro/qemu-from-laptop/qemu/build/arm-asan/../../hw/char/max78000_uart.c:241:5
Add an instance_finalize method to destroy the FIFO.
