depthcharge: Fix a firmware update failure in Netboot
During netboot ,the 'chromeos-firmwareupdate' uses 'futility update' to
update the AP & EC firmware (Please refer to CL:1343618).
The futility would call 'mosys' which needs to read FDT node
"/proc/device-tree/firmware/chromeos/nonvolatile-context-storage" to get
the correct platform information.
Unfortunately deptcharge does not export it into device tree and the
firmware update process in netboot would fail.
This CL would call crossystem_setup() in depthcharge stage of netboot
firmware to export some mandatory nodes into device tree.
BUG=b:125176300
TEST=1.) Build netboot firmware of flapjpack locally
2.) Do the netboot process and check the firmware had been
updated successfully.
