drm: adv7511: Fix DDC error interrupt handling
The DDC error interrupt bit is located in REG_INT1, not REG_INT0. Update both the interrupt wait code and the interrupt sources reset code accordingly. Cc: stable@vger.kernel.org Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
