Remove the device tree from one of the vboot support APIs.
This change removes the device tree from one of the vboot support APIs so
that they fit better with coreboot u-boot. Specifically this is
cros_gpio_fetch which is for getting GPIO values. Coreboot will read these and
provide the values through its coreboot tables. The device tree pointer is
global data so it doesn't need to be passed around as a parameter to be
accessible.
This change also removes the device tree from other interfaces in
cmd_vboot_twostop.c so the structure of the code is more consistent. This way
people can expect the device tree to always be the one pointed at by the
global data and not sometimes one and sometimes the other, even though as
written those will be equivalent. This change also takes the opportunity to
mark the local functions in that file static, which is most of them.
