Added 1.1 schematic

Version 1.1 fixed a few minor issues that do not affect function of the
board (some filter caps were routed incorrectly) as well as some minor
improvements to speed up board assembly.
Removed the FAULT/ALERT/SPI LEDs as they didn't prove useful during
firmware dev/debug.
Replaced hotplug limiting resistors on _S, _N, and MCU lines with 4 part
arrays.
