google/chromeec: Do not set wake mask before logging EC events
Earlier the EC expected the host to set appropriate masks before
reading host events. However, with recent change in EC, this is no
longer required. This change removes the setting of wake_mask before
and after reading the host events. However, in order to support older
versions of EC, a new feature flag is added on the EC side that
informs the host whether or not it is using the new way of reporting
host events without having to set wake mask.
CQ-DEPEND=CL:719578
TEST=Verified that EC wake events are correctly logged with both old
and new versions of EC.
