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-5.4/017-PCI-aardvark-Improve-link-training.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.
 target/linux/ath79/patches-5.4/921-serial-core-add-support-for-boot-console-with-arbitr.patch

These patches needed manually changes:

Subject: [PATCH] net: mscc: ocelot: refactor struct ocelot_port out of
function prototypes
The ocelot_port structure has a net_device embedded in it, which makes
it unsuitable for leaving it in the driver implementation functions.
Leave ocelot_flower.c untouched. In that file, ocelot_port is used as an
interface to the tc shared blocks. That will be addressed in the next
patch.
