pd_policy: Change DP AltMode event from host event to MKBP.
Previously, the EC could notify the AP that it had entered into
DisplayPort Alternate mode by sending a MODE_CHANGE host event.
However, there was no mechanism to disable that functionality if desired
without effecting the other MODE_CHANGE events (i.e. - base
attach/detach). By changing the DisplayPort Alternate mode entry to an
MKBP event, we can have more granularity and only affect this single
event.
- This commit adds a new MKBP event, EC_MKBP_EVENT_DP_ALT_MODE_ENTERED.
- The commit also changes the DP AltMode entry notification from sending
a MODE_CHANGE host event to this new MKBP event.
