This patch series attempts to implement basic support
for Ultrajoiner functionality.
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.
