Ville Syrjälä ca62297b20 drm/edid: Fix csync detailed mode parsing
Remove the bogus csync check and replace it with something that:
- triggers for all forms of csync, not just the basic analog variant
- actually populates the mode csync flags so that drivers can
  decide what to do with the mode

Originally the code tried to outright reject csync, but that
apparently broke some bogus LCD monitor that claimed to have
a detailed mode that uses analog csync, despite also claiming
the monitor only support separate sync:
https://bugzilla.redhat.com/show_bug.cgi?id=540024
Potentially that monitor should just be quirked or something.

Anyways, what we are dealing with now is some kind of funny i915
JSL machine with eDP where the panel claims to support a sensible
60Hz separate sync mode, and a 50Hz mode with bipolar analog
csync. The 50Hz mode does not work so we want to not use it.
Easiest way is to just correctly flag it as csync and the driver
will reject it.

TODO: or should we just reject any form of csync (or at least
the analog variants) for digital display interfaces?

v2: Grab digital csync polarity from hsync polarity bit (Jani)
