Jason A. Donenfeld 196f3d586f 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`.

Subject: [PATCH] Revert "mtd: spi-nor: fix Spansion regressions (aliased with
Winbond)"
This reverts commit 67b9bcd36906e12a15ffec19463afbbd6a41660e.
The underlying issue breaking Spansion flash has been fixed with "mtd: spi-nor:
wait until lock/unlock operations are ready" and "mtd: spi-nor: wait for SR_WIP
to clear on initial unlock", so we can support unlocking for Winbond flash
again.
