[PATCH 1/7] platform/chrome: cros_ec_typec: No pending status means attention

[Stephen Boyd <swboyd@chromium.org>]

If we aren't expecting a status update when
cros_typec_displayport_status_update() is called then we're handling an
attention message, like HPD high/low or IRQ. Call
typec_altmode_attention() in this case so that HPD signaling works in
the DP altmode driver.
