[PATCH 00/15] Ultrajoiner basic functionality series

[Ankit Nautiyal <ankit.k.nautiyal@intel.com>]

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

Patches 1-2 are re-posts from https://patchwork.freedesktop.org/series/138751/

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.

Rev9:
Rebase

Rev10:
-Rebase
-Fix enable_joined_pipes as suggested by Ville, to avoid propagate
is_ultrajoiner.
-Enhance the mask to iterate over joiner pipes, as suggested by Ville.
