2014-01-07[media] adv7842: obtain free-run mode from the platform_dataMartin Bugge
The free-run mode can be board-specific. Also updated the platform_data in ezkit to ensure that what was the old default value is now explicitly specified, so the behavior for that board is unchanged.

2014-01-07[media] adv7842: restart STDI once if format is not foundMartin Bugge
The STDI block may measure wrong values, especially for lcvs and lcf. If the driver can not find any valid timing, the STDI block is restarted to measure the video timings again. The function will return an error, but the restart of STDI will generate a new STDI interrupt and the format detection process will restart. Copied from adv7604.

2014-01-07[media] adv7842: 625/525 line standard jitter fixMartin Bugge
Both the PAL and NTSC standards are interlaced where a frame consist of two fields. Total number of lines in a frame in both systems are an odd number so the two fields will have different length. In the 625 line standard ("PAL") the odd field of the frame is transmitted first, while in the 525 standard ("NTSC") the even field is transmitted first. This adds the possibility to change output config between the fields and standards. This setting will reduce the "format-jitter" on the signal sent by the pixelport moving the difference between the fields to vertical front/back-porch only.

The method of disabling the irq-output pin caused many "empty" interrupts. Instead, actually disable/enable the interrupts by changing the interrupt masks. Also enable STORE_MASKED_IRQ in INT1 configuration, otherwise when HDMI events happen while the interrupt is masked those events will be ignored when the interrupt is unmasked.
