Vic Yang dbb55cb1f4 Keyborg: implement system reboot

In case the slave got into a bad state, we may need a way to reboot the
slave from the master. The protocol must not involve SPI communication;
otherwise this will fail if the slave SPI module is in a bad state.

This CL implements this using SPI_NSS. In normal SPI communication, the
master pulls SPI_NSS low and immediately sync with the slave. To reboot
the slave, the master pulls SPI_NSS low without the following sync.

BUG=None
TEST=Reboots the slave from the master.
BRANCH=None
