HW: position of microSD may impact existing case designs

Created by: jadonk

Because the microSD card cage orients cards flipped from BeagleBone Black, some existing case designs may not allow for the microSD card to be inserted or removed as previously designed. For rev A2, we plan to move the microSD card cage 1mm closer to the microHDMI such that the travel path for the microSD card will be more similar to that on BeagleBone Black, despite the orientation change.
