ccd: 'pp polling' vendor command option
When implementing 'ccd open' and 'ccd unlock' through gsctool, we need
to be able to pass to the host the state of the physical presences
state machine regarding the expected user action (pressing the PP
button).
Two new VENDOR_CC_CCD subcommands are being added: CCDV_PP_POLL_OPEN
and CCDV_PP_UNLOCK. In response to these commands, the Cr50 always
returns VENDOR_RC_SUCCESS return code and a single byte payload
showing the CCD and PP state:
- CCDPP_CLOSED - PP process is not running, CCD closed. Maybe user
missed a button press deadline.
- CCDPP_AWAITING_PRESS (self explanatory)
- CCDPP_BETWEEN_PRESSES (self explanatory)
- CCDPP_PP_DONE - CCD is opened/unlocked (as per user request), PP
process succeeded.
BRANCH=cr50
BUG=b:62537474
TEST=with the upcoming change to gsctool verified that PP states are
properly conveyed to the user.
