gma: Do not check for hot-plug events on analog port
The corresponding bits in PCH_ADPA reflect the current state of the
connection and not a change in the state. This was interpreted wrong
since some PRMs state that these bits can be cleared. It seems they
can't be, though. Linux' i915 also doesn't try to clear them and only
interprets their state as presence of a display.
