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.

+Grey-scale image as a MIPI RAW14 packed array
+
+
+Description
+===========
+
+This is a packed grey-scale image format with a depth of 14 bits per
+pixel. Every four consecutive samples are packed into seven bytes. Each
+of the first four bytes contain the eight high order bits of the pixels,
+and the three following bytes contains the six least significants bits of
+each pixel, in the same order.
+
+**Byte Order.**
+Each cell is one byte.
