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] mtd: spi-nor: Add support for mx25r3235f
Add MTD support for the Macronix MX25R3235F SPI NOR chip from Macronix.
The chip has 4MB of total capacity, divided into a total of 64 sectors,
each 64KB sized. The chip also supports 4KB large sectors.
Additionally, it supports dual and quad read modes.
Functionality was verified on an HPE/Aruba AP-303 board.
