mb/google/hatch: Add a GPIO to enable/disable FPMCU power
A FPMCU power-control pin (GPP_C11) is added to the latest
hatch reference schematic.
Even though this is not implemented in hatch rev1 board, the future
hatch family boards with FPMCU should all have this control pin.
On the old boards without this control pin, GPP_C11 is a floating TP,
and thus this patch should be backward-compatible.
