Misc: Fix doxygen comment for MaxPower field with respect to super-speed
The MaxPower field of a configuration descriptor is in units of 8 mA
when the device is operating in super-speed mode according to the USB
3.0 specification, section 9.6.3, table 9-12:
Maximum power consumption of the device from the
bus in this specific configuration when the device is
fully operational. Expressed in 2-mA units when the
device is operating in high-speed mode and in 8-mA
units when operating at Gen X speed.
(i.e., 50 = 100 mA when operating at high-speed and
50 = 400 mA when operating at Gen X speed).
Adjust the doxygen comment for the MaxPower member of struct
libusb_config_descriptor accordingly.
Closes #69
