hosted: Consolidate the code that polls the battery charging status

affects all hiby targets, fiiom3k, and ibasso dx50/dx90

As well as deduplicating a small pile of code, this also implements
hysteresis so we're not doing a sysfs read/lookup multiple times
back-to-back every time the power management tick fires.
