Douglas Anderson 6ec52621e7 drm/panel-simple: Don't wait longer for HPD than hpd_absent_delay 
If a panel has an hpd_absent_delay specified then we know exactly how
long the maximum time is before HPD must be asserted.  That means we
can use it as a timeout for polling the HPD pin instead of using an
arbitrary timeout.  This is especially useful for dealing with panels
that periodically fail to power on and need to be retried.  We can
detect the problem sooner.
