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] LF-368 net: mscc: ocelot: add VCAP IS2 rule to trap PTP
Ethernet frames
All the PTP messages over Ethernet have etype 0x88f7 on them.
Use etype as the key to trap PTP messages.
