The Buffalo Linkstation LS421DE has a chassis fan for cooling two internal
hard drives. Currently there is no control over this fan, running always
at fixed medium speed.
With the recent jump to the kernel 5.4, now we can monitor the hard drive
temperature and control the fan with thermal zones.
Install the kmod-hwmon-drivetemp module and wire up a thermal zone on the
dts file to allow automatic fan control by the kernel.
Tested succesfully using a single Crucial BX500 SSD drive.

- Delete useless HDD presence inputs: they aren't buttons, and probably
they are outputs in the stock firmware.
- Change the Function Button keycode: the current one isn't mapped by
the kernel module.
- Use the recommended property names for the ethernet stuff.
- Add missing i2c pinmux.
- Minor cosmetic changes.

The DTS files in files-4.19 and files-5.4 are exactly identical
except for one file (armada-3720-uDPU.dts), which is only present
for 4.19, as it has been upstreamed before 5.4.
Since there is no point in maintaining all these identical files
twice, this patch moves them to the "files" directory, only keeping
the named exception to files-4.19.
