Hauke Mehrtens 14940aee45 kernel: bump 5.4 to 5.4.163

 target/linux/mvebu/patches-5.4/016-PCI-aardvark-Train-link-immediately-after-enabling-t.patch

The following patch does not apply to upstream any more and needs some
more work to make it work fully again. I am not sure if we are still
able to set the UART to a none standard baud rate.
