Patrick Rudolph d323d844f7 util/autoport: Improve USB code
Currently autoport fills in USB current '0' if the detected setting
isn't one of the known settings. This works as 0 is a valid setting
from C point of view, but it's not supported on desktop PCs and on
mobile platform results in the lowest possible USB PHY gain. Thus
this might cause instabilities as the original firmware had stronger
USB drive currents and gain settings.

Add more known USB current fields to the map and generate a FIXME
as comment when the detected current isn't one of the known entries
instead of defaulting to 0.
