acpi/ec: Handle new host event EC_HOST_EVENT_BODY_DETECT_CHANGE
Handle the new host event EC_HOST_EVENT_BODY_DETECT_CHANGE.
Previously, the EC sent the host event EC_HOST_EVENT_MODE_CHANGE when
body detection changed between lap/desk mode. However, that event is a
wake event, which resulted in spurious AP wake events being triggered
when the EC detected lap/desk mode changes while the AP was suspended.
To resolve this, the new host event EC_HOST_EVENT_BODY_DETECT_CHANGE was
added, which will not be a wake event. This CL adds handling for the new
event to acpi/ec.asl to switch DPTC tables when a change is detected.
BRANCH=none
BUG=b:261141172
TEST=bodydetectmode on|off, verify host event is received
