cr50: expose spihash PP polling to the host
When running the spihash command using gsctool (as opposed to the
running it from the Cr50 console), the operator needs to be prompted
when the PP button needs to be pressed.
This patch extends spihash command implementation by adding a new
subcommand for polling physical presence.
BRANCH=cr50, cr50-mp
BUG=b:73668125
TEST=with the appropriate gsctool changes the user is periodically
prompted to press the physical presence button, and eventually it
is possible to set up spi hash access to AP and EC.
