Subject: [PATCH 5.10 305/663] platform/chrome: cros_ec_proto: Add LID and BATTERY to default mask

From: Evan Benn <evanbenn@...omium.org>

[ Upstream commit 852405d8efcbca0e02f14592fb1d1dcd0d3fb508 ]

After 'platform/chrome: cros_ec_proto: Use EC_HOST_EVENT_MASK not BIT'
some of the flags are not quite correct.
LID_CLOSED is used to suspend the device, so it makes sense to ignore that.
BATTERY events are also frequent and causing spurious wakes on elm/hana
mt8173 devices.

Fixes: c214e564acb2 ("platform/chrome: cros_ec_proto: ignore unnecessary wakeups on old ECs")
