commit 6562d6e350284307e33ea10c7f46a6661ff22770 upstream.
The regulator reg_rst_eth2 should keep the reset signal of the USB ethernet adapter deasserted anytime. Fix the polarity and mark it as always-on.
Anyway, using the regulator is only a workaround for the missing support of specifying a reset GPIO for USB devices in a generic way. As we don't have a solution for this at the moment, at least fix the current workaround.
