[PATCH] drm/xe: Move Wa 1607983814 to oob

needs_wa_1607983814() predates wa_oob, so it was not being printed
in /sys/kernel/debug/dri/0/*/workarounds. Port it to OOB rules.
This makes the WA show up in debugfs. For TGL:

	OOB Workarounds
		22012773006
		1409600907
		1607983814

Eventually the RTP infra may add support for writing registers in a
loop, which would allow to keep track of the registers as well. But for
now, just listing it as OOB workaround is already an improvement.
