Hauke Mehrtens 14940aee45 kernel: bump 5.4 to 5.4.163
Removed upstreamed:
 target/linux/mvebu/patches-5.4/001-PCI-aardvark-Wait-for-endpoint-to-be-ready-before-tr.patch
 target/linux/mvebu/patches-5.4/016-PCI-aardvark-Train-link-immediately-after-enabling-t.patch

 target/linux/mvebu/patches-5.4/020-arm64-dts-marvell-armada-37xx-Set-pcie_reset_pin-to-.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.

Subject: [PATCH] drivers: net: mscc_ocelot: don't flood unicast traffic to cpu
Switch cpu port doesn't learn MAC addresses and the local bridge dev_addr
must be explicitly added to the bridge.
This is done whenever a port is added to a bridge, ports following the
1st one will just overwrite the same entry.
