Rev6: -Upgrade the debugfs functionality to enable the joining of a specified number of pipes. -Modify the display helpers reliant on the pipe joiner mechanism to use number of pipes joined, instead of joiner flag. -Checkpatch fixes. Rev7: -Use struct intel_display, minor refactoring, and rebase. Rev8: -Address comments from Ville. -Simplified debugfs for forcing joiner, and added option to disable joiner. -Modified the ultra/bigjoiner helpers as suggested by Ville. -Split few of the bigger patches as suggested.
