Several hosted targets read their battery state from a fixed
sysfs path. Get rid of the duplicated code by handling this
common case in power-linux.c.
Some targets use non-standard units in sysfs instead of the
typical microvolts / microamps, so allow the scale factors
to be overridden by the target.

Battery time estimation works now.
This commit also changes the mksquashfs path to FUNKEY_SDK_PATH.

Actually power off the handheld with the sleep timer and idle poweroff functions instead of closing rockbox.
This commit also moves setting system volume to max from the launch script to system-sdl.c so it works when running rockbox via instant play.

Instant play is a Funkey OS feature that allows it to relaunch at boot the last program it was running before shutting down, which means that if the handheld is powered off (holding the power button) while rockbox is running the next time it's powered on rockbox will launch at boot.
This commit also handles system brightness/volume in rockbox itself instead of the launch script, so the values are properly reset when powering off the handheld while rockbox is running.

A bit of context, this device is a clone of the FunKey-S with a different form factor, hardware is mostly identical, the relevant difference is it has audio out (via usb-c, adapter to 3.5mm is included), this is the reason why the FunKey-SDK is needed for bulding.
This port is based on the old SDL 1.2 code because the device doesn't have SDL2 support. Alongside what was supported in the SDL 1.2 builds this port supports battery level, charging status and backlight control.
