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

Subject: [PATCH] can: flexcan: rename macro FLEXCAN_IFLAG_MB() ->
FLEXCAN_IFLAG2_MB()
The macro FLEXCAN_IFLAG_MB() is always used for the iflag2 register, so
rename it to FLEXCAN_IFLAG2_MB()
