J. Hancock
Made all resistors 1%, replaced 3.3V regulator with
MIC37100, removed VBUS_UP and REGEN DNP resistors,
removed I2C reference as configuration option, and added
SMBus addresses to slave devices.

Depopulated pull-up resistor on ALERTn, populated 0Ohm J. Hancock
on ALERTn to USB chip, added RC circuit to PPWR3_H
between USB and UCS chip, added EEPROM, and wired
ESD diodes to 5V instead of VBUS on downstream ports.
