kernel: bump 5.4 to 5.4.114

Removed because in upstream*
  mvebu/patches-5.4/319-ARM-dts-turris-omnia-configure-LED-2--INTn-pin-as-interrupt-pin.patch

Manually rebased*
  generic/backport-5.4/700-v5.5-net-core-allow-fast-GRO-for-skbs-with-Ethernet-heade.patch

Added new backport*
  generic/backport-5.4/050-gro-fix-napi_gro_frags-Fast-GRO-breakage-due-to-IP-a.patch

All others updated automatically.

The new backport was included based on this[1] upstream commit that will be
mainlined soon.  This change is needed because Eric Dumazet's check for
NET_IP_ALIGN (landed in 5.4.114) causes huge slowdowns on drivers which use
napi_gro_frags().

Compile-tested on: x86/64, armvirt/64, ath79/generic
Runtime-tested on: x86/64, armvirt/64, ath79/generic
