Created by: JacobPease
- Added help option to the flash-sd script.
- Added ability to specify device tree to flash-sd. It also will generate the device tree files inside the specified buildroot directory
- Fixed order of binary variables so that they're defined with the specified buildroot location.
- Prevented writes to SATP enabling SV57. This follows the spec more accurately. Linux can now successfully probe SATP.
