kernel-5.4: bump to 5.4.102 and refresh patches
5.4.102 backported a lot of stuff that our WireGuard backport already
did, in addition to other patches we had, so those patches were
removed from that part of the series. In the process other patches were
refreshed or reworked to account for upstream changes.
This commit involved `update_kernel.sh -v -u 5.4`.
