Dan Ehrenberg 7c2beb0838 cgpt: Separate out certain GPT manipluation functions
For kernel NAND support, some vboot/cgptlib functionality is
needed from depthcharge. This patch moves certain function
declarations to a new header in firmware/include and puts
their definitions in a common place.

TEST=make runalltests passes and packages build
