box mod

For people who don't want to buy the adapter, here is the modification to supply the eMMC from the box:

Remove R3, R6 and re-route the pins 17 and 19 to the internal regulators U7 and U6. This means we will have VCCQ 1.8V on pin 19 and VCC 3.3V on pin 17.
WARNING, remember that you will have ALL THE TIME this two voltage on the connector, so use this 2 pins ONLY and ONLY when dealing with eMMC direct!
