vboot: Clean up vboot code

1. Remove unused functions/structures.
2. Add checks for NULL return values.
3. Change prefixes to vb2 instead of vboot for functions used internally
within vboot2/
4. Get rid of vboot_handoff.h file and move the structure definition to
vboot_common.h
5. Rename all functions using handoff structure to have prefix
vboot_handoff_*. All the handoff functions can be run _only_ after cbmem
is online.
6. Organize vboot_common.h content according to different
functionalities.
