Vadim Bendebury d5e598646d cr50: configure GPIOs properly
The SPS GPIOs are hard wired, so there is no need to configure the
mux, but the default mode of pin operation is "output". The three SPS
input pins (CLK, CS, and MOSI) need to be explicitly configured as
such.

BRANCH=none
BUG=chrome-os-partner:50141
TEST=spiraw and TPM tests now pass
