The spshc command switches the protocol on the SPI Slave bus to
expect EC Host Commands.

TEST=manual
At the EC console:
spstpm off
spshc
On the build machine, with an FTDI cable connected to the SPS
input:
cd extra/ftdi_hostcmd
make
./test_cmds

This CL also adds a test example in the extra/ftdi_hostcmd/
directory. To use it, you need the Cr50 attached to the build
host via an FTDI USB-to-SPI adapter.
