Revert "drm/i915: Declare the swizzling unknown for L-shaped configurations"
This reverts commit 19ee835cdb0b5a8eb11a68f25a51b8039d564488. It breaks existing old userspace which doesn't handle UNKNOWN swizzling correct. Yes UNKNOWN was a thing back in 2009 and probably still is on some other platforms, but it still pretty clearly broke the testers machine. If we want this we need to extend the ioctl with new paramters that only new userspace looks at.
