drm/dsi: transfer DSI HS packets ending at the same time
Since a HS transmission is composed of an arbitrary number
of bytes that may not be an integer multiple of lanes, some
lanes may run out of data before others.
(Defined in 6.1.3 of mipi_DSI_specification_v.01-02-00)
However, for some DSI RX devices (for example, anx7625),
there is a limitation that packet number should be the same
on all DSI lanes. In other words, they need to end a HS at
the same time.
Because this limitation is for some specific DSI RX devices,
it is more reasonable to put the enable control in these
DSI RX drivers. If DSI TX driver knows the information,
they can adjust the setting for this situation.
