d5cc74ebd8 build: Get rid of suplerflous '-Os' references in linker calls 
We should be using global optimization flags, and -Os is already our
default.

555299af9f 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.

Once some missing power optimization stuff was added to the X3ii code,
they were completely identical.
