John Audia ec6293febc kernel: bump 5.4 to 5.4.109
Ran update_kernel.sh in a fresh clone without any existing toolchains.

Manually rebased:
  pending-5.4/611-netfilter_match_bypass_default_table.patch

The upstream change affecting this patch is the revert of an earlier
kernel commit. Therefore, we just revert our corresponding changes
in [1].

Build system: x86_64
Build-tested: ipq806x/R7800

[1] 9b1b89229f ("kernel: bump 5.4 to 5.4.86")

Subject: [PATCH] arm64: dts: ls104x: make dma-coherent global to the SoC
These SoCs are really completely dma coherent in their entirety so add
the dma-coherent property at the soc level in the device tree and drop
the instances where it's specifically added to a few select devices.
